Do-it-yourself aerodynamic exhaust pipe. Making a muffler nozzle with your own hands

In auto parts stores, there are always a large abundance of auto mufflers and nozzles that imitate a muffler with a huge diameter and are covered with a cane or stainless steel. So at least any owner will simply be able to choose the right type of nozzle or muffler for his car brand, not counting the fact that if you have a special car or taste, then everything that your heart desires will be brought to you on order. The most fascinating thing is that consumer demand for these attachments does not subside, but periodically also increases, respectively, manufacturers do not stand still, and merchants constantly keep the assortment in a variety.

And a very fascinating question arises, why is this
Is a small and slightly noticeable element so necessary among drivers? Nozzle
albeit small, but makes the rear view of the car much more noticeable, dark
from soot, the exhaust pipe becomes shiny, larger in diameter and
directs attention to itself, especially if there are two of them. This partly raises
authority to the car, visually natural, but still, such pipes make
the effect of a tuned and powerful exhaust system. If the car is outside
supplement with various spoilers and body kits, which are now in abundance, then
the car from a simpleton is transformed into a unique sports car, but again, only
visually.

There is a type of attachments that not only change the outside
the look of the car, and one hundred percent change the sound of the exhaust system. it
achieved thanks to a special perforated insert inside the nozzle,
which, in addition to everything, is also regulated, making the sound higher or lower. Holder
can set the sound you like and simulate the work of any massive V8
engine, although in reality under the hood there will be the most ordinary 1.6 liter. On
some models, on the contrary, just by the way has the sound of a high-speed racing
car, tall and sibilant, like a Formula car.

In addition to the template sound options, there are also such mufflers,
which generally allow you to customize the sound for personal requirements, in such
resonators are installed in the nozzles, they change the sound according to the spectra. It is for
especially demanding car enthusiasts who were not satisfied with the sound option from
past nozzles, well, either for those who are bored with the monotony and longs for
once a day to hear a different song of your own car.

Homemade
muffler

Surely, there is nothing that gambling could not do
do-it-yourself car owner, at the moment there are a huge number of examples of attachments, various
shapes, diameters and internal structures, because from what to choose and for what
to look at problems does not appear. The most popular and needed nozzle -
this is a traditional type, there are no resonators and membranes in it, this
a nozzle for a pleasant external perception, instead of steel and smoked and
improvement of certain properties, about them below. This version of the nozzle is able to make
in fact, anyone who wants to without the help of others.

A stainless steel metal with a width of 1 is better than even 2 mm,
which must be bent so that it gets the shape of a cone. Dimensions and diameter
products will depend on the size of the true exhaust pipe and of course on
car models. Then boil the resulting cone along the joint, and so that the edge
the cone got strength, drill four holes in it along the diameter
5-10 mm on each side, and an iron ring must be put on the end of the cone.
It remains only to hoist this nozzle on exhaust pipe, after that it is necessary
squeeze under the diameter of the native muffler, this is done with clamps and brackets, which
are completely tightened with bolts and will not allow the structure to fly off. Works
a similar nozzle in the following way: it has an expanding profile at the end,
which allows you to create a vacuum in the muffler, a large diameter gives
the ability for gases to swirl and this makes a certain sound.

What else is the usefulness of the nozzle, not counting the outdoor decoration, although
naturally and it is just necessary from time to time. Apart from this, there is also a practical
usefulness, for example, accelerated removal of exhaust gases from the exhaust system and
even from the motor. This is due to the combination of air currents,
when the car is driving at a speed of 40 km / h and above, the air flow around makes
a huge difference in pressure inside and outside, which speeds up the withdrawal. As a result
there is an improvement in the operation of the cylinders, they are perfectly blown, the remains
are displayed faster, because the freshest fuel mixture enriched with oxygen for
much better, as a result of this, the motor power noticeably increases from 10 to
20%.

Another fundamental point is the absence of carbon deposits on the candles,
cylinders, pistons and piston heads, which is decently accumulated and
disables these parts. What's catchy, having a power boost
unit, it also saves fuel, thanks to the balanced work of the purge
cylinders and motor. In addition, the car gets a new sound, not that
tense and torn, but a muffled and measured roar.

But it's worth stepping aside and talking about some problematic
moments. Not all attachments will be equally good, you need to choose and make them with
awareness, tk. in certain cases, they can harm the engine,
though not essential. Not every muffler is necessary for the best purging to arm
nozzle, another time it must be completely changed, for example, install
sports muffler. An incorrectly matched nozzle can reduce
properties of the motor, reduce power due to the fact that gases will have to
push forward on a complicated nozzle, it will take a couple of% of the power.

So that you have guidelines, the dimensions will be given below
nozzles depending on the volume of the motor.

• If you have a 1000 cc / cm unit, then the nozzle is needed less
  15 cm, with all this its diameter is 30-35 mm.
• A 1600 cc unit asks for a 20 cm nozzle with
  with a diameter of 38-42 mm.
• In turn, by 1800 cc / cm you need to make the length up to 28
  cm, and the diameter is 48-52 mm. Well, and accordingly, with a huge volume, you need to do
  nozzles more than 30 cm long and up to 63 mm in diameter.

In addition to its appearance, its sound when driving is of great importance for the image of a car. Many owners are not very powerful gasoline engines seek to amplify the sound, resorting to tricks like installing extras on the exhaust system. The exhaust muffler with the sound of the turbine does not make the car more powerful, but it does improve its sound.

The addition that is installed on the exhaust pipe is otherwise called a whistle, resonator or turbo whistle. It is essentially an improved whistle. Its principle of operation is as follows: at high engine speeds, it makes its tone as similar as possible to a turbine whistle.

To get the best effect from a muffler tip with turbine sound, you need to choose the right whistle. It depends on the following parameters:

• engine volume;
• exhaust pipe diameter.

Types and sizes

Muffler tips with turbine sound are available in the following sizes:

• S - for a motorcycle or scooter;
• M - for Vehicle with a volume of up to 1.4 liters;
• L - for cars with a volume of up to 2.2 liters, diameter - 43-56 mm;
• XL - for vehicles with an engine capacity of 2.3 l and more, diameter - more than 57 mm.

The dimensions of the devices for installation in the exhaust pipe are given for good reason. When installing an unsuitable whistle, there will be no buzzing, or it will be completely uncharacteristic for a powerful "engine".

Another feature: even if you clean the muffler and install it on a small car, where the engine volume is about 1 liter, such a turbo whistle, high-quality and loud buzz will be much more difficult to achieve than on a more powerful car.

To understand how to make a whistle for a muffler with your own hands, please note that its shape is:

• rectangular;
• conical;
• cylindrical.

Silencer attachment with turbine sound is adjustable by sound. For this, its cylindrical or conical part is unscrewed. And the change in sound occurs due to the fact that holes are located inside it through which exhaust gases flow. Kit for imitation expensive car includes:

• stainless steel whistle;
• the bracket to which it is attached;
• bolts, nuts, washers and grovers;
• key with 6 faces.

Manufacturing procedure

To find out how to make a whistle for a muffler with your own hands, you need to make a list of the required tools and materials. You will need:

• angle grinder or electric jigsaw with a blade for cutting metal;
• automotive tools;
• sandpaper;
• electric drill;
• cardboard;
• stainless steel 1 mm thick.

Most car owners strive to continually improve their vehicle. This is expressed in constant or periodic tuning. And if someone prefers the inner more, there are many adepts and external tuning... This includes the nozzle for the muffler of the car. This detail has several positive effects.

Purpose and device

Such a nozzle, when installed, carries several tasks at once:

1. First of all, the nozzle acts as an element of car tuning... The exhaust system is quite visible to the outside eye. Therefore, many tuning enthusiasts pay attention to this detail when carrying out it. The nozzle can visually increase the size of the exhaust tract, and give the car "brutality". Also, with the help of such a nozzle, you can change quite a lot appearance the back of the car and give it a personality. That is why this type of tuning has earned quite a lot of popularity;
2. Also, the nozzle can significantly change the sound of the exhaust system. Every car enthusiast will be able to appreciate the "angry roar" of the exhaust system, even on a small car. This is achieved by special inserts inside such nozzles, which change the sound of the exhaust at the outlet and pipe;
3. Despite the relatively low cost of such products and a huge assortment, a certain category of motorists prefers to independently manufacture such attachments.

The whole process is not particularly difficult, only if you have certain skills, necessary materials and great experience, therefore for ordinary motorists the most the right way there is still the acquisition of such attachments. Moreover, this applies to the situation when it is necessary to make such a nozzle with additional illumination. In this case, the owner of the car must, in addition to locksmith skills, also have knowledge in the field of electrical engineering.

Manufacturing process

The most popular material for the manufacture of such attachments is, of course, metal. It is best suited if the metal is stainless (treated with an anti-corrosion compound). This will allow you to use such a nozzle for a long time (the average service life will leave about 5 years). Moreover, in rare occasions aluminum is used, however, such a metal has a number of disadvantages - low temperature melting, ease with mechanical deformation. Stainless steel is best suited for making the nozzle.

The manufacturing process of the nozzle itself takes place in several stages:

1. To begin with, the size of the future nozzle is measured... This is done using special measuring instruments relative to the standard location of the muffler. The diameter of the nozzle should be only slightly larger than the regular space, so that it can sit tightly on seat;
   Then the corresponding steel billet is purchased (it can also be carved out of a steel blank with your own hands, although this process will take quite a long time). The cost of such a blank will be incomparably lower than the price for a finished product, therefore, if you have turning skills, buying a blank is more than rational;
2. After that, the processing of the resulting product begins.... To appearance the bit was indistinguishable from an industrial part and must be carefully sanded. For this, special industrial machines are used. The processing time directly depends on the degree of skill of the owner of the nozzle and usually takes about half an hour;
   After that, you need to try on the resulting part on a standard exhaust system. If any shortcomings appear, they must be promptly eliminated;
3. Then you should start installing the backlight... To do this, you need a diode tape of a certain length (depending on the diameter of the backlight).

• Then it is necessary to conduct the wiring to the power source (on-board network) and power diode tape from the battery.
• It is also necessary to provide an algorithm for turning on the backlight (from the ignition or from a button on the panel). After that, you need to check the system for performance.

On the forums, car owners are increasingly asking which is better and easier - do-it-yourself muffler nozzle or store. You will find the answers to this question in the article.

Why do you need a muffler attachment?

Before trying on another innovation on your car, you should definitely figure out what the benefit will be from it. One of the biggest challenges exhaust system- overheating of the metal and the presence of aggressive exhaust. In addition, everything gets dirty in the lower part of the car from road dirt. As a result of this triple effect, the new exhaust system turns into a pitiful sight in a matter of weeks. Considering that we constantly have to contemplate only the end of the exhaust, then, decorating it with an original nozzle, we will solve the aesthetic problem.

A DIY muffler attachment, made in a garage or purchased from a store, performs several other important tasks.

The original decoration at the end of the muffler will definitely lead to a change, and if you install it inside the nozzle LED backlight, then the color will also change exhaust gases... However, this is not the most important function of the nozzle. As you know, aerodynamic forces affect a car in motion. The air that moves around the car creates increased pressure on its front and sides, but a vacuum zone forms at the back.

If you increase the size of the outlet of the muffler, the pressure difference between the outside of the pipe and the inside will be higher. Thus, the exhaust gases when driving at speed will be "drawn" from the pipe, and this will definitely improve ventilation. What can this give? Testing has shown that this effect leads to savings and improved dynamics, namely:

• Fuel burns better;
• less carbon deposits form on candles and other surfaces;
• power increases;
• fuel consumption is reduced by up to 20%.

How to make a muffler nozzle with your own hands in a garage?

Understanding how useful a small metal element can be for a car makes you look for an opportunity to make a nozzle. It is more interesting to do it yourself than to buy a ready-made one. In addition, the cost savings become apparent after familiarizing yourself with the prices of similar products in car dealerships.

To work, you need to acquire a set of simple materials and tools:

• fragment of stainless steel suitable size thickness of about 1 mm .;
• cardboard;
• an angle grinder with a cutting disc or a jigsaw with a blade for cutting metal;
• electric drill;
• set of automotive tools;
• sandpaper and polishing materials.

There are several options for making a muffler nozzle in shape. The body of the nozzle can be cone-shaped, rectangular or square, and also in the form of a cylinder. On the Internet you can find detailed description manufacturing of each of the types. The manufacturing principle is the same, the nozzle itself is performed in the following sequence:

• using a piece of cardboard, the nozzle body is modeled, taking into account the fastening and connecting elements;
• the finished paper model is unfolded and a template is made from it;
• the body is cut from a piece of stainless steel according to the template;
• the workpiece is carefully bent, the joint is riveted, welded or bolted;
• the finished product is cleaned and polished to a mirror finish.

Features of mounting a nozzle for a muffler

Having dealt with the question of how to make a muffler, you can install it on the end of the pipe and start the motor. Attached nozzle different ways: through the hinges with a bolt and through hole in a pipe or a tie in the form of a clamp. In the place of attachment, it is better to lay a refractory material in the form of an asbestos thread. This will protect the structure from overheating and provide additional sealing.

In any case, the method of fastening should ensure easy dismantling of the product in the future. This is necessary for periodic cleaning of the housing from carbon deposits. The service life of stainless parts is much longer than that of a muffler made from conventional steel. When changing the muffler, the nozzle can be used again.

The muffler is an important part of the entire exhaust system. In addition to being responsible for the emission of exhaust gases, it also significantly reduces the noise level from the operation of the car engine.

It should be understood that the exhaust system as a whole for each car is a unique mechanism with a complex geometry and individual operating parameters. However, many modern car enthusiasts decide to resort to tuning the muffler to make their car more unique, sportier and brighter than the rest. The muffler has tremendous tuning potential.

Most often, tuning a muffler consists in installing a nozzle, bifurcating or wiring the muffler, changing the sound and increasing the total engine power.

In the latter case, we are talking about a very complex technical process, which is almost impossible to carry out with your own hands. In general, the matter is quite interesting, but it is worth dwelling on the muffler in more detail, since most of the exhaust system itself is hidden under the bottom of the car, which makes the process of its modernization much more difficult than directly tuning the muffler. A variety of all kinds of nozzles that are offered on the market allows you to create a unique muffler design for any car model, on a foreign car or domestic car.

Nozzles come in different materials and different price category... Most popular on domestic market enjoy stylish stainless steel. These attachments are easy to maintain and add style to your car. Fans of more extravagant solutions also choose attachments with additional illumination, which look great in the dark. In addition, there are two types of attachments, simple and with sound.

If we talk about nozzles that change the sound of the muffler, which are also called resonators, then their installation is no different from the installation of conventional nozzles. As a rule, special fasteners, clamps and bolts are included with ready-made resonators, however, better fastening of the nozzle to the muffler can be achieved by welding. Welding allows you to reliably fasten this decorative element to the muffler, this gives a guarantee that the nozzle will not get lost on the road, because from strong vibrations the bolts with clamps will loosen over time, and the resonator will simply fall off.

Some car enthusiasts prefer to make their own attachments. This requires a set of additional tools and a piece of metal, preferably stainless steel. At self-made nozzles must be sized correctly, which directly depends on the volume and power of the engine. In the standard version of a car with an engine volume of 1.6 liters and an output not exceeding 120 Horse power the size of the nozzle must be at least 20 centimeters in length and at least 40 mm in diameter. But if you want the attachment not only to create a unique sound, but also to be a bright addition to the style of the car, then it is better to purchase a ready-made version.

First of all, you need to evaluate the material. Cheap pads are usually covered with additional material in the form of chrome or nickel, but this quickly deteriorates, in addition, the strength of the metal also plays an important role, since a fragile nozzle can deform, for example, during parking. If the nozzle is damaged, it must be replaced, otherwise there is a risk of a drop in engine power and a decrease in the efficiency of the entire exhaust system.

If you buy a resonator, you should definitely make sure of the sound quality. You can listen to the tonality of a particular resonator model from your dealer. Do not hesitate, because this sound will now accompany you on every trip by car, so if you do not like it, it is reasonable to choose another part with a better and more sporty sound. The sound in this case is influenced by several factors, including the diameter of the nozzle, the inner filler and the shape of the edges of the nozzle.

It is also important to remember that the choice of a nozzle or another method of tuning the muffler depends on many factors, including the model and make of the car, engine settings and the geometry of the exhaust system of foreign cars. Not every purchased or self-made nozzle will fit a certain type of muffler for foreign cars, and this should also be taken into account when buying. Installing a high-quality nozzle on a car muffler for foreign cars will make the car and its owner stand out from the crowd. High-quality sound, lighting - all this will perfectly complement the image of any car. Well, those for whom a pleasant sound and beautiful bulbs are not enough can turn to specialized ateliers, in which not only the muffler, but also the entire exhaust system can be completely altered.
