Crank up the intensity and let your twin-turbo V8 breathe free with the Untd. Performance Catless Downpipe for the Audi C8 RS6 and RS7. Designed for unrestricted power and unfiltered sound, this downpipe removes factory catalytic converters to deliver maximum flow, faster turbo response, and a raw exhaust note that transforms your RS into a true performance weapon.
By eliminating the stock catalytic converters, this downpipe drastically reduces backpressure and unlocks the full potential of your EA825 4.0T. Expect quicker spool, sharper throttle response, and substantial gains in horsepower and torque—especially when paired with a proper ECU tune.
Going catless brings the beast to life. Experience a louder, deeper, and more aggressive sound with enhanced turbo spool, sharper crackles, and a race-inspired note that dominates under throttle. It’s the kind of presence that turns heads—and keeps them turned.
Crafted from TIG-welded 304 stainless steel with smooth mandrel bends and CNC-machined flanges, this downpipe is built for extreme temps and high-boost abuse. It’s engineered for consistent, leak-free performance under the most demanding conditions.
Designed for the C8 chassis, this downpipe offers a clean, factory-style fit with no cutting or modification required. Works seamlessly with OEM and most aftermarket cat-back systems for a smooth install.
Intended for off-road and motorsport applications, this downpipe is perfect for serious builds where emissions compliance isn’t required. Whether you’re chasing dyno numbers or building the ultimate track machine, this is the upgrade that sets the tone.
