High Flow Catalytic Converter (HFC) for B8 Audi A4, A5, Q5 2.0 TFSI - 034-105-4023

Product Description:

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.

Features:

• Stainless Steel Tubing
• TIG Welded
• Application-Specific Flanges
• Factory Oxygen Sensor and Exhaust Hanger Placement
• Installation Hardware Included!
• Dyno-Proven Horsepower and Torque Gains!

We've seen gains of over 24WTQ and 27WHP on our dyno on stock turbo tunes.
