Unlock raw, unfiltered performance from your Audi S6, RS6, S7, or RS7 (C7 platform) with the Untd. Performance 2.75″ Catless Downpipe. Purpose-built for the twin-turbo 4.0T V8, this downpipe removes the restrictive factory catalytic converters to maximize exhaust flow, unleash horsepower, and transform your driving experience. Whether you’re carving corners or chasing numbers on the dyno, this downpipe delivers the performance, sound, and response you’ve been looking for.
The Untd. Performance 2.75″ Downpipe removes the factory catalytic converters, significantly reducing backpressure and allowing your twin-turbo V8 to breathe freely. Expect faster turbo spool, stronger throttle response, and a noticeable increase in horsepower and torque across the rev range.
With the catalytic restrictions gone, the 4.0T V8 comes to life with a deep, aggressive exhaust note. The turbo spool becomes more audible, and crackles on deceleration are sharper and more pronounced—delivering a race-inspired soundtrack that’s impossible to ignore.
By improving turbo efficiency and exhaust gas velocity, this downpipe delivers real-world performance benefits. Turbo lag is minimized, throttle response becomes crisp, and the car pulls harder through the powerband—ideal for high-performance builds and enthusiast-level driving.
The 2.75″ mandrel-bent tubing and CNC-machined flanges ensure a perfect fit to the OEM turbo and mid-pipe. This downpipe is a direct bolt-on replacement that installs cleanly with no cutting or welding required.
Constructed from premium 304 stainless steel, the Untd. Performance Downpipe is built for durability and longevity under extreme conditions. TIG-welded for strength and reliability, it’s designed to handle the high heat and pressure of a tuned 4.0T V8 engine.
This downpipe is engineered for track cars, dyno builds, and enthusiast applications where emissions compliance isn’t required. With no catalytic converter, it’s optimized for maximum flow and performance in off-road environments.
