The purpose of the installation of a sport exhaust system is to make it easier for exhaust gases to go out. A standard exhaust system does not ensure a proper flow of gas. Each curvature or fumes cleaning element makes their exhaust slower. Stainless steel, smooth and very durable material downpipes are made of, together with the removal of all possible obstacles and increasing the diameter of the pipe, facilitate the exhaust outlet.
A downpipe is an element located just behind the exhaust manifold in naturally aspirated engines or behind the turbocharger in supercharged engines. It improves the work quality of the turbine, which has a direct impact on the car performance, especially on the angular momentum. A pass-through pipe with a sport catalytic converter or with full passage can be used to accelerate the movement of the exhaust gas.
