Description
Overview
Meet the perfected B9 S4 soundtrack. The AWE Tuning Touring Edition Exhaust System Kit for the 2018-2025 Audi S4 (3.0) delivers the signature AWE howl in its most sophisticated form. Engineered as a true Cat Back performance exhaust, this system replaces the restrictive factory piping with mandrel-quality construction and a refined acoustic character that stays civil within the cabin while cruising, yet erupts with pops and burbles during acceleration and downshifts.
The Touring Edition is the most sophisticated member of the B9 S4 exhaust family. Rather than relying on physical valves, it removes the factory valving entirely and installs AWE’s 180 Technology drone-cancelling resonators along with electronic valve simulators. The result is a perfectly balanced car exhaust experience: comfortable at highway speeds and unmistakably aggressive when you get on the throttle.
Key Benefits
Built from T304L Stainless Steel, this exhaust system is designed for durability and lasting corrosion resistance under real-world driving conditions. The 2.5-inch tubing feeds a quartet of 4-inch Chrome Silver tips for a clean, premium look at the rear of your S4. Because this is a no-valve design, you get consistent tone without the mechanical complexity, and there is no tune required to run it.

Sound & Technology
What sets this borla-alternative AWE performance exhaust apart is the 180 Technology drone-cancelling design.
