Unleash hidden power and bring your 2.0T to life with the Untd. Performance 3″ Catless Downpipe for the Audi A4, A5, and Q5 (B8/B8.5 chassis). Designed to replace the restrictive factory downpipe, this high-flow, catless upgrade drastically improves exhaust flow, enhances turbo spool, and adds a more aggressive tone—giving your Audi a true performance edge both on the street and at the track.
The factory catalytic converter is one of the biggest bottlenecks in your 2.0T’s exhaust system. Our catless downpipe removes that restriction and opens the system up with free-flowing 3″ mandrel-bent stainless steel tubing. The result? Reduced backpressure, quicker turbo response, and increased power throughout the RPM range.
With the cat removed, your turbocharged engine gets a stronger, more dynamic voice. Enjoy a deeper exhaust tone, more pronounced turbo spool, and sharp pops on throttle lift. It’s the sound of boosted performance—and it’s all yours.
Expect a noticeable bump in horsepower and torque, especially when paired with a tune. Faster turbo spool and improved exhaust scavenging mean better throttle response and stronger pull in every gear. It’s the perfect first step for any performance build.
Constructed from high-grade 304 stainless steel, the Untd. Performance Downpipe is built to handle extreme heat and long-term abuse. Precision TIG welds and CNC-machined flanges ensure a leak-free, durable fit that’s ready for the street or strip.
This downpipe is designed for easy, direct-fit installation on B8 and B8.5 2.0T models. It bolts right up to the factory turbo and exhaust system with no cutting or welding required. All hardware is included for a smooth install.
This downpipe is intended for off-road use where emissions equipment can be removed. It’s ideal for race builds, dyno tuning, or enthusiast-driven cars in regions where emissions compliance is not required.

The Untd. Performance 3″ Catless Downpipe is the ultimate bolt-on upgrade for your B8/B8.5 2.0T. From faster spool to a stronger tone and increased power, it’s everything your turbo four-cylinder needs to break free and perform at its peak.
⚠️ Note: For off-road and track use only. Not emissions-compliant in all regions. Check local regulations before installation.
