CAP Audi 2.0T Resonated Catback Exhaust System | 2015–2020 8V / 8V.5 Audi S3 The best sounding 2.0T exhaust in the world. Engineered for Sound. Built for Performance. The 8V / 8V.5 Audi S3 is one of the most tunable and responsive 2.0T platforms on the market, but the factory exhaust system significantly restricts the engine’s true sound and performance potential. CAP set out to develop a catback exhaust system that strikes the perfect balance between aggressive performance, sound, and refined daily drivability. After extensive real-world testing and acoustic refinement, the CAP Audi 2.0T Catback Exhaust System was engineered to unlock the true character of the EA888 engine—delivering a deep, sporty tone under throttle while maintaining a comfortable, drone-free experience during cruising. Introducing the CAP Resonated Catback Exhaust System, a complete exhaust solution for the 8V / 8V.5 Audi S3 is a complete performance upgrade designed to maximize both sound quality and exhaust flow. Designed to Work With Your Setup Many Audi S3 owners upgrade their vehicles with high-flow or catless downpipes, which can often introduce excessive rasp and harsh tones when paired with typical aftermarket exhaust systems. The CAP Resonated Catback Exhaust System was designed to maintain a balanced and refined tone, even when paired with higher-flow exhaust components. Combo Pairing When paired with the CAP Catless Downpipe, the exhaust produces a smooth tone creating one of the best sounding exhaust combinations for the 8V/8V.5 S3 platform.
