Description
Overview
The Audi (3.0) Exhaust System Kit from AWE Tuning is a post-cat downpipe engineered to replace the factory resonated downpipes and unlock a cleaner, more refined exhaust flow. Built from durable T304L stainless steel with a larger-than-stock 2.5-inch tubing diameter, this Resonated Downpipe is designed to bolt directly into place and pair seamlessly with existing AWE exhaust setups — or work with your factory system if you’re keeping things stock out back.
Unlike many performance exhaust upgrades, this AWE downpipe requires no tune and carries a No CEL Guarantee, so you get a genuine performance exhaust system component without the headaches of a check-engine light or supporting software. It’s also 50 State Legal, making it a smart choice for owners who want proven AWE quality and a legally compliant upgrade.
Resonated Sound, Dialed In
AWE offers both Resonated and Non-Resonated Downpipes, and this is the Resonated version. It features resonators larger than the stock units to deliver a mellow, controlled sound volume. AWE strongly recommends the Resonated Downpipes for S-tronic cars when paired with the AWE Touring Edition Exhaust — the combination is built for ultimate sophistication and drone control. If you’re chasing a louder, more aggressive character, AWE’s optional Non-Resonated downpipes are the alternative, but the Resonated route keeps the cabin refined at cruise.

Pairing & Fitment
These post-cat downpipes replace the factory resonated downpipes and pair directly to existing AWE exhausts. They also work with the factory exhaust if you want to keep the rear of your car exhaust setup stock. In limited cases, the factory downpipes have been known to emit minor rattling noises when paired with the AWE S4 3.0T exhaust system — adding an AWE downpipe eliminates that possibility entirely, giving you a quieter, better-integrated exhaust system.
Whether you’re building toward a full catback exhaust configuration or simply want a stronger foundation for your current AWE exhaust, this downpipe is the connective piece that ties the system together. When you shop for exhaust upgrades for your 3.0-liter Audi, this AWE Tuning downpipe delivers the engineering, fitment confidence, and refined sound control that serious owners expect from a premium performance exhaust brand. Choose the Resonated configuration for the most sophisticated, drone-managed result — especially on S-tronic cars matched with the Touring Edition Exhaust.
