CAP Audi 2.0T Catback Exhaust System | 2015–2020 Audi 8V / 8V.5 S3

Precision Engineered Sound. Maximum Flow. Pure 2.0T Performance.

The Audi 8V / 8V.5 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.

Many aftermarket systems either produce an overly aggressive, raspy tone or fail to deliver the deep, refined sound enthusiasts expect from a performance vehicle. 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.

This system transforms the driving experience of the Audi S3 while maintaining the build quality and precision fitment CAP products are known for.

Introducing the CAP Catback Exhaust System

The CAP Catback Exhaust System for the Audi 8V / 8V.5 S3 is a complete performance upgrade designed to maximize both sound quality and exhaust flow while retaining a clean OEM-style fit.

Unlike many aftermarket options that focus solely on sound, this system was engineered to improve overall exhaust efficiency, throttle response, and turbo performance.

Designed to bolt directly after the factory catalytic converter, the system integrates seamlessly with:

• OEM catalytic converter

• High-flow aftermarket downpipes

• Aftermarket test pipes
