Why enthusiasts choose this S3 8V Sportback exhaust upgrade

• Made from premium 304 grade stainless steel with beautiful TIG welds. Hand finished in Sheffield.

• Choice of sound level. Resonated retains the centre silencer for a refined, sporty note. Non-resonated removes the centre silencer for a louder, more aggressive soundtrack.

Non-valve control design

This system removes the factory valve control. Drive modes will no longer alter the exhaust loudness. There is no impact on engine health or drivability. The acoustic profile has been tuned to deliver an engaging tone without unwanted harshness.
