AWE Tuning Audi B9 S4 Touring Edition Exhaust - Non-Resonated (Silver 102mm Tips)

Worn-out exhaust systems cause a loss of power and an undesirable drone. This AWE Tuning Touring Edition Exhaust is a direct fix for your 2018-2024 Audi S4. It replaces the factory valving with AWE's 180 Technology resonators, giving you a sophisticated exhaust note that's quiet inside the cabin but still lets you hear the pops and burbles when you get on the throttle.

This cat-back system is handcrafted from dual 2.5-inch U.S.-sourced T304L stainless steel with a .065-inch wall thickness. It includes post-catalyst downpipes and a precision X-pipe. The straight-through design maximizes performance, and AWE claims gains of up to 16 hp and 17 lb-ft of torque at the crank. It's designed to bolt directly on, just like the factory exhaust, and won't trigger a Check Engine Light.
