Product description:
The HPerformance 4 inch 101.6mm downpipe comes directly from the development of our 1/4 mile vehicle into series production. It is the first downpipe in the world to be built in this pipe diameter throughout. It starts at the turbo outlet and replaces the standard pre-catalytic converter. Our TÜV downpipe comes with 2 x 400 cell catalytic converters, which can be used far beyond the TÜV-approved range (600 hp) and also uses OPF filters. We also install this variant in the approved power levels with 707 hp in all OPF models.
The downpipe goes in exchange for the standard downpipe. Especially with the OPF models, there is a clearly noticeable difference between 3.5 inch / 88.9mm and 4 inch / 101.6mm in exhaust back pressure and temperature recordings. On average, the exhaust backpressure of the 4-inch OPF downpipe is another 119 millibars (mbar) below the level of a 3.5-inch variant. The exhaust gas temperature under continuous load with the 4-inch variant is on average 15 °C below the 3.5-inch variant.
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.
