The G-Tuning company has been professionally engaged in the design and manufacture of exhaust systems and components for many years.

Accumulated experience  allows us to realize any wishes of customers. Our company has unique equipment for the production of mufflers and resonators made of stainless steel and titanium. We bend exhaust pipes using a mandrel pipe bending machine, which ensures high quality bending without changing the pipe diameter.

All our products are made of AISI 304 stainless steel.

Each component goes through a series of tests and quality control before being sold or installed on a car.

Car exhaust system

With a modern engine, it is often enough just to remove the artificial restrictions laid down from the factory in order to fully reveal the capabilities of even an absolutely standard engine and achieve a quite tangible increase in power and torque. The exhaust system with straight-through catalytic converters, resonators and mufflers, well-thought-out inter-pipe jumpers for multi-cylinder, especially V-shaped engines, is, along with easier intake and a change in the engine program, the first step in the so-called “Stage 1” level of technical tuning of the engine.

The exhaust system of an atmospheric (in the English-speaking world — naturally aspirated) engine makes a significant contribution to its dynamic characteristics, power and torque distribution depending on the crankshaft speed.

Thus, only the exhaust system can give the same engine a completely different character: from uniform traction almost from idle to explosive pickup at the top, something similar to "turning on the turbine" with complete indistinctness in the lower rev range.

Development of exhaust systems.

With a deep refinement of the naturally aspirated engine, the regular exhaust begins to literally choke the engine. The entire exhaust system has to be literally developed anew, taking into account its new characteristics and the desired nature of work: the geometry of the exhaust manifold, the dimensions and volumes of direct-flow catalysts, middle and rear mufflers, the diameter and length of the pipes and connecting jumpers between them. An incorrect calculation of at least one element can bring all the work of fine-tuning the motor to naught or radically change its character. The principle "the more – the better" in the case of a naturally aspirated engine, it does not work, especially if the target is an elastic engine with a wide operating speed range. In this case, you need an understanding of the processes taking place in the engine and exhaust, calculations and, of course, experience.

An important factor when creating an exhaust system is the desired exhaust sound. The major automakers, especially their "charged" divisions (such as Quattro GMBH, AMG, BMW M, etc.), there are separate sound studios that deal exclusively with exhaust sound tuning. When developing an exhaust system from scratch, the sound of the engine will also have to be dealt with from scratch, taking into account the new engine characteristics, geometry and consistency of all components of the exhaust system. Recall the characteristic "gurgling" Subaru sound. This is not a feature of the boxer engine (the same boxer Porsches have the usual smooth sound of work), but the result of using an unequal exhaust manifold. And again, calculations and experience are needed.

The development of exhaust systems for turbocharged or compressor exhaust systems is much easier than for atmospheric ones. The presence of forced pressurization eliminates the need to consider such processes as back pressure, as well as the geometry and location of the middle resonators and silencers — the turbine itself is already a fairly effective muffler. The principle “the more the better” becomes the key one, in which, however, it is still necessary to take into account the geometry of the system, if only for the sake of the exhaust sound, on which the geometric dimensions of the components used have a direct influence.
