Downpipe 2.7L Bi-turbo for Audi S4 RS4 76mm > 63.5mm Stainless Steel with Flex Pipe

-Stainless Steel Downpipe 76>63.5mm with Flex Pipe for Audi S4 RS4 B5 2.7 Biturbo*

Description:

The stainless steel ø 63.5mm downpipe significantly reduces back pressure, relieving the turbos which in turn provides more power and lowers exhaust temperatures. The post-catalyst sensor may need to be programmed out. The downpipe is made of stainless steel. The flange surfaces are planed. Two lambda probe connections M18x1.5mm are welded in. The downpipe starts from turbo ø 76mm and tapers down to 63.5mm with integrated flex pipes. The connection pipes to the exhaust are as original. The downpipe is located between the turbocharger and the exhaust. Installing two 200-cell catalytic converters is recommended. A performance up to max. 500HP can be achieved, of course, the other components such as exhaust system, fuel injectors, manifold, intercooler, turbocharger must be installed and the software adapted accordingly. The downpipe is simply replaced 1:1 with the original.
