Manufacturer: 034Motorsport

034Motorsport B8 S4 3.0T FSI test pipe downpipes are designed to replace the restrictive OE catalytic converters, and increase horsepower and torque throughout the powerband. These downpipes were developed to stand up to the rigors of Grand-Am racing, and used on the APR Motorsport B8 Audi S4 3.0 TFSI.

Our downpipes are constructed from 2.25" diameter, 0.109" 304 thick wall stainless steel tubing, and designed to eliminate the factory catalytic converters entirely. They feature CNC machined flanges to prevent warping and expansion, factory-correct exhaust hanger location, and 2 oxygen sensor bungs in the proper locations for the factory sensors. Professionally assembled in-house, TIG-welded and backpurged.
