034Motorsport High-Flow Catalytic Converters are designed to replace the restrictive factory catalytic converter, and allow for quicker spool while increasing horsepower and torque throughout the powerband.

We construct them from stainless steel tubing, and utilize a high-performance 250-cell stainless-steel-matrix cat. They feature precision 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 throughout.

Complete drop-in upgrade; will bolt up to any stock/stock-fit turbo and stock/stock-fit exhaust. Professionally assembled in-house, TIG-welded.

*** Direct bolt-in for OEM cat-back exhaust, or aftermarket cat-back exhaust systems designed to fit with the OEM catalytic converter. Will fit Quattro and FWD B7 Audi A4 2.0T FSI models equipped with Manual, Tiptronic, or CVT transmissions. ***
