What is the difference between the resonated and non-resonated Touring Edition exhausts?

The non-resonated version, like this one, offers a more aggressive sound profile with pops and burbles. The resonated version includes additional mufflers to further cancel cabin drone for a more refined cruising experience.

Does this exhaust require any modifications for installation?

No, this is a direct bolt-on system designed for factory-like installation. It includes all necessary components like the x-pipe and post-catalyst downpipes, and is guaranteed not to cause a Check Engine Light.

What is AWE's 180 Technology®?

180 Technology® is AWE's proprietary drone-cancelling solution. It uses internal baffling within the resonators to reflect sound waves, canceling out unwanted low-frequency drone inside the vehicle while still allowing for an aggressive exhaust note.

Product Details

AWE Tuning makes this Touring Edition Exhaust for the 2018-2024 Audi S4. This system replaces your factory valving with AWE’s 180 Technology® resonators, which cancel out drone inside the cabin. You get a civil sound when cruising, but all the pops and burbles you want when you get on the throttle.

This exhaust is built from dual 2.5-inch, .065-inch wall T304L stainless steel tubing. It’s CNC mandrel-bent for smooth flow. The system includes post-catalyst downpipes and a precision-engineered x-pipe. AWE builds these systems in-house in the USA.
