DOWNPIPE,B7 A4 HFCHIGH FLOW C

034Motorsport High-Flow Catalytic Converters are designed to replace the restrictive factory/OE catalytic converter, allowing for quicker spool and increasing horsepower and torque throughout the powerband. They are constructed from 304 stainless steel tubing and utilize a high-performance 250-cell stainless-steel-matrix cat. They feature precision CNC machined flanges to prevent warping and expansion, factory-correct exhaust hanger location, and two oxygen sensor bungs in the proper locations for the factory sensors. Full 3" tubing is used throughout. This is a complete drop-in upgrade that will bolt up to any stock/stock-fit turbo and stock/stock-fit exhaust system. Professionally assembled in-house, TIG-welded and backpurged, and includes installation hardware. Dyno-proven horsepower and torque gains of over 27WTQ and 33WHP on stock turbo tunes.
