Make your RS3 stand out with our exclusive oversized black RS-style oval tips. These tips fill the factory cutouts perfectly, giving your car a supercar-inspired look that commands attention.
Factory Valve Sound Control:
The system retains the factory exhaust valve operation through your vehicle’s drive select modes. Enjoy quiet, civilized driving in Comfort mode or unleash an aggressive 5-cylinder roar in Dynamic or RS mode—no compromises needed.
Quality Construction:
Manufactured from premium T304L stainless steel, all components are mandrel bent and precision TIG welded by hand to ensure longevity and flawless fitment. This exhaust system is built to last a lifetime.
Installation Notes:
-
