Description
Overview
The 15-20 Audi S3 (2.0) Exhaust System Kit from AWE Tuning delivers smooth bends, tight packaging, and two distinct attitudes in one handcrafted cat back exhaust system. Built around the SwitchPath™ Edition, this performance exhaust pairs a valved passenger-side tip outlet with U.S.-sourced T304L stainless steel construction, giving your S3 the ability to whisper through town or sing a signature AWE tune at the flick of a valve.
SwitchPath™ retains the factory valve behavior, obeying the S3’s ECU commands based on throttle input, engine speed, and Drive Select. Sneaking out in the morning or creeping through the neighborhood? Close the valve. Ready to rip? Toggle into Dynamic and your S3 wakes up with enhanced crackles that provoke a firm grin. Whether you’re cross-shopping a Borla exhaust, Corsa exhaust, or MagnaFlow exhaust, this AWE catback exhaust stands out for keeping full factory-style control while adding real character.
Key Benefits
Handcrafted from 3-inch and 2.5-inch T304L stainless steel tubing, this exhaust system is engineered for durability and clean flow. It’s a Cat Back system that requires no tune, carries a No CEL Guarantee, and is backed by AWE’s Fit Guarantee — so installation and daily driving stay hassle-free. The 50 State Legal voluntary label means it’s built to keep you compliant, and it ships without needing 180 Technology or additional programming.

Options & Control
While SwitchPath™ is designed to work with the factory controls, you can add the AWE SwitchPath™ remote for push-button mood control any time you want to open or close the valve on your own terms. And if you ever decide to go full-rowdy all the time, AWE made it easy to convert between SwitchPath™ and Track Edition down the road — a simple way to change your volume without starting over. The tips come standard as 102mm double-walled, slash-cut units, here featuring the Diamond Black finish complete with the stamped AWE logo.
Fitment
This exhaust pipe kit is engineered specifically for the 2015-2020 Audi S3 (2.0). If you’ve been searching to shop for exhaust upgrades or comparing a Walker exhaust or other car exhaust options for your S3, this AWE catback exhaust is the new standard for Audi’s skyrocketing small sedan — combining refined daily manners with a bold, dynamic voice.
