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 304 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.
Features:
- Stainless Steel Tubing
- TIG Welded
- Application-Specific Flanges
- Factory Oxygen Sensor and Exhaust Hanger Placement
- Dyno-Proven Horsepower and Torque Gains!
- We've seen gains of over 26WTQ and 15WHP on our dyno on stock turbo tunes.
Fitment:
- 2005.5 - 2008 Audi A4 2.0T FSI (B7)
*** 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. ***
Please Note: Installation gasket and hardware kit and oxygen sensor spacer available as options.
- Gasket & Hardware Kits - We have pieced together all of the necessary parts to make swapping out your factory catalytic converter a breeze. This kit includes turbo outlet and cat-to-midpipe gaskets, as well as all necessary nuts and bolts for a complete install.
- Oxygen Sensor Spacer - This spaces out the secondary (rear) O2 sensor to remove MIL or CEL issues caused by removing the factory catalytic converter. Professionally manufactured from stainless steel, not cobbled together by hand like some other products on the market. Spacer will add approximately 1.7" to the height of the sensor. 034Motorsport oxygen sensor spacers feature a flare seal seat, so no sealing washer or gasket is required.
