034Motorsport High-Flow Catalytic Converter / B8 Audi A4 / A5 / Allroad / Q5 2.0T

034Motorsport High-Flow Catalytic Converters are designed to replace the restrictive OE 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 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 3.5" tubing is used at the turbo outlet, with a smooth transition to 3" after the cat.The high-flow catalytic converter 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.
