Key Features:

200 Cell High-Flow Catalytic Converters

Equipped with premium 200 cell sport cats, this downpipe dramatically improves exhaust flow compared to stock, while helping reduce emissions and minimize CEL risk. The high-flow design supports big power and works perfectly with stage 1 or 2 tuning setups.

Integrated Heat Shielding

Engineered with built-in thermal shielding to manage radiant heat, this downpipe keeps engine bay temperatures in check, protecting sensitive components and maintaining consistent performance under aggressive driving and high-boost conditions.

Sharper Sound, Cleaner Tone

Unleash the signature growl of the 4.0T V8 without going over the top. The catted setup provides a deeper, more aggressive exhaust note with enhanced turbo spool and subtle crackles—while avoiding the rasp and harshness of a full catless system.

Power You Can Feel

Reduced backpressure means quicker spool, stronger midrange punch, and smoother power delivery throughout the rev range. Perfect for tuned RS6/RS7 builds looking for consistent gains with a more street-friendly sound profile.

Built to Perform

Constructed from TIG-welded 304 stainless steel with CNC-machined flanges, this downpipe is built to withstand extreme temps, high boost, and long-term use. It’s the same motorsport-grade durability you expect from every Untd. Performance product.

Direct Bolt-On Fit

Precision-engineered for the C8 RS platform, this downpipe installs seamlessly using factory mounting points. Compatible with both stock and aftermarket exhaust systems.
