Detailed Description

The Milltek Sport 76 mm Cat-Back Exhaust is a precision upgrade for RS3 Sportback (MQB Facelift) owners who prioritize tone, build quality, and fitment finesse. Designed to replace the factory rear section, it maintains structural integrity while imparting a sharper, more aggressive exhaust note—especially under throttle.

You have the flexibility to choose a resonated option for more refined tone or a non-resonated “race” variant for a louder, more visceral sound. The inclusion of premium tailpipe finishes like titanium or burnt finishes elevates the aesthetic, making the rear end pop.

Built specifically for the MQB Facelift platform, this exhaust system fits cleanly using factory mounts and hardware. No cutting, bending, or fabrication is required—just bolt it on and enjoy.
