Milltek Cat-Back Exhaust System – Mini Cooper S R53 2002–2006

The Milltek Sport Cat-Back Exhaust System is designed for first-generation Mini Cooper S R53 models from 2002 to 2006. The system replaces the original exhaust system after the catalytic converter, offering improved flow, a sportier sound profile, and high-quality finish.

Milltek Sport exhaust systems are known for their high manufacturing quality and precise fit. The Cat-Back system is an excellent upgrade for both standard and tuned R53s when the goal is to improve exhaust gas flow and achieve a slightly more aggressive yet controlled sound.

Benefits of a Cat-Back System

Upgrading to a Cat-Back exhaust system is an effective way to improve the exhaust flow of your R53 without needing to modify the catalytic converter. A larger and more efficiently flowing exhaust system reduces exhaust back pressure and gives the supercharged Cooper S a sportier character.

Milltek has designed the system to work with the R53's original engine and exhaust system, making it well-suited as a bolt-on upgrade.
