Upgrade your Audi 8V RS3 or 8Y RS3 or 8S TTRS 2.5T with a high-performance race rs3 downpipe, that engineered to eliminate restrictive factory catalytic converters, enhancing exhaust flow for maximum performance. Delivers an impressive 50+ HP and 70+ TQ gain when properly tuned, while providing an aggressive exhaust note and a perfect fit.

Developed using advanced 3D scanning and CAD simulation, this 8y rs3 downpipe optimizes exhaust routing for smooth, unrestricted flow. The design ensures exhaust gases split evenly into dual 2.5-inch outlets from a large 4.0-inch 8v rs3 downpipe outlet, improving turbo efficiency and power delivery.

Cel Delete Kit / Cel Eliminator / O2 Sensor Spacer

The installation of catless downpipes will result in an inevitable check engine light (CEL) as the DME will detect that emissions are not being burnt up by the OEM catalyst. To remove this CEL without having to tune it out we offer the CEL Delete Kit which is comprised of O2 sensor spacers specifically calibrated to comply with BMW's parameters for a functioning catalyst. These install into the post-catalyst O2 sensor bungs, effectively removing the CEL that would otherwise appear.
