Product description:

The HPerformance 4 inch 101.6 mm downpipe comes directly from the development of our 1/4 mile vehicle to series production. It is the first downpipe in the world to be built with this pipe diameter throughout. It starts at the turbo outlet and replaces the standard pre-catalytic converter. Depending on which variant you order, you will either have no catalyst, two 100 cell catalysts or two 400 cell catalysts (our TÜV variant).

The pipe diameter reduces the exhaust back pressure by up to 30% (depending on the boost pressure, the turbocharger and other peripherals) and thereby massively reduces the tendency of the engine to "knock" on cylinders 2 and 3 - which begins at the latest at 700hp on 102 octane and 820hp on E85. During our turbocharger development we were able to determine several times that the difference between 3.5 inches (88.9mm) and 4 inches (101.6mm) resulted in up to 20hp and 25NM, as well as a reduction in the exhaust back pressure by up to 0.15 bar, even with a downpipe directly on the floor of the vehicle.

These advantages are now also available for the road, as the downpipe has been made ready for series production. 

Any change to catalytic converters (replacement, change of cells or size - different from the original state) requires a software adaptation of the engine control unit. With our remote flash solution, we also offer suitable tuning for the DNW 2.5 TFSI.

Important: Race Downpipes do not have TÜV approval and may not be used legally on public roads
