Unleash the raw character and performance potential of your Audi TTRS 8J with the Untd. Performance Catless Downpipe, specifically engineered for the legendary 2.5T DAZA inline-five. By eliminating the restrictive factory catalytic converter, this race-inspired downpipe dramatically improves exhaust flow, reduces turbo lag, and amplifies the signature five-cylinder growl that defines the TTRS driving experience.
Catless High-Flow Design
Designed to completely remove the factory catalytic converter, this downpipe reduces backpressure and unlocks the full performance capabilities of the turbocharged 2.5L engine. The result is increased horsepower, torque, and faster spool—especially under hard acceleration and at higher boost levels.
Sharper Turbo Response & Power Delivery
With exhaust flow dramatically improved, turbo lag is minimized and throttle response becomes immediate. Expect a more responsive, aggressive powerband—ideal for both tuned daily drivers and full track builds.
Unfiltered, Motorsport-Inspired Sound
Eliminating the cat gives the DAZA engine its full voice. The result is an unmistakable, raw five-cylinder note with deeper tone, aggressive overrun pops, and increased turbo acoustics. Every drive becomes an event.
Race-Grade Construction
Crafted from TIG-welded 304 stainless steel with CNC-machined flanges, this downpipe is built to handle extreme heat, pressure, and abuse from high-performance driving. It’s designed for perfect fitment and long-term reliability on the street or at the track.
Optimized for Tuning
This downpipe lays the groundwork for serious performance tuning. Whether paired with a Stage 2+ ECU flash or a custom-built turbo setup, it provides the unrestricted flow needed to push the limits of the DAZA platform.
