Details

When you want faster spool and increased horsepower and torque through the powerband, then the High Flow Catalytic Converter manufactured by 034 Motorsports is your solution. Their high flow cats replace the more restrictive OEM cat. This high flow cat fits the Quattro, Audi A4 1.8T, Passat B5 1.8 or FWD B5 or B6 equipped with a CVT, Tiptronic or manual tranny. This replacement bolts in and comes with the same oxygen sensor and exhaust hanger placement as the factory. It replaces the original cat or an aftermarket cat-back with the OEM catalytic converter.

EuroSport Tuning only sells parts we would put on our own cars and brands we believe in, so you are getting a part that we recommend.  We offer fast shipping and same day fulfillment in most cases.

Product Overview

034 Motorsport High Flow Catalytic Converters (HFC) are designed to replace the restrictive OE catalytic converter, and allow for quicker spool while increasing horsepower and torque throughout the powerband. This HFC fits Quattro and FWD B5 & B6 Audi A4 1.8T plus the Passat B5 1.8T models equipped with manual, Tiptronic, or CVT transmissions. Direct bolt-in for OEM cat-back exhaust, or aftermarket cat-back exhaust systems designed to fit with the OEM catalytic converter.

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-mid pipe 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.
