Description
Overview
The AWE Tuning 18-25 Audi S4 (Sedan – 3.0) Exhaust System Kit is a purpose-built Cat Back performance exhaust engineered for drivers who want their S4 to sound as serious as it drives. Built as a Track Edition, this exhaust system carries the same precision-engineering as AWE’s Touring Edition counterpart, but strips away the resonators up front and the 180 Technology resonators in the rear. In their place you’ll find non-resonated downpipes and straight pipe sections, leaving the integrated x-pipe as the only filter in the entire car exhaust. The result is an aggressive, unmistakable voice that AWE openly warns is known to get rowdy.
Key Benefits
Crafted from durable T304L Stainless Steel with 2.5-inch tubing, this catback exhaust is designed to stand up to hard usage and deliver a lasting performance edge. Because it requires no tune and carries a No CEL Guarantee, installation stays straightforward — no check engine lights, no recalibration, just bolt on and drive. It’s also backed by a Fit Guarantee and carries a 50 State Legal voluntary label, so you can shop for exhaust upgrades with confidence that this system is dialed in for your S4.
When it comes to the finishing touch, the Track Edition wraps up with a quad-tip layout of four 102mm slash-cut tips in a Chrome Silver finish, each stamped with the AWE logo so everyone knows what team you’re on. Every one of the 4-inch tips is individually adjustable, letting you set the depth into the bumper according to personal taste. They’re double walled, too, ensuring a mirror finish that holds up even when you’re pushing hard.

Fitment
This exhaust pipe kit is engineered specifically for the 2018-2025 Audi S4 Sedan with the 3.0 engine. As a Cat Back performance exhaust, it replaces the system from the cats back and integrates the x-pipe as the sole sound filter, making it a dramatic step up from the factory car exhaust.
A Note Before You Buy
The Track Edition is loud by design. AWE describes it as one that gets rowdy, and it may be too much for many drivers — so much so that this particular version cannot be returned due to sound preference. If you like it loud and want the most uncompromising exhaust system AWE offers for the S4, go Track. Prepare yourself.
