034Motorsport Catless Testpipes are designed to replace the restrictive OE catalytic converter, and allow for quicker spool while increasing horsepower and torque throughout the powerband.
Constructed from stainless steel tubing for optimal flow, 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. Full 3" tubing is used from the turbo outlet to the downpipe flange.
The catless testpipe is a complete drop-in upgrade; will bolt up to any stock/stock-fit turbo and stock/stock-fit exhaust. Professionally assembled in-house, TIG-welded and backpurged.
