Milltek Sport was founded by car enthusiasts for car enthusiasts. Based in the UK, their products are developed and tested at their development center at Nurburgring in Germany. The result is a wide range of top of the line exhaust systems that can bring more life to your car!
Performance to blow your mind, not your ears! Improve performance and your vehicle's sound with this cat-back exhaust system from Milltek.
Milltek engineers took on the task of finding the perfect balance between maximum performance increase and a responsible noise level in each and every system, to appeal to enthusiasts of all levels. All products are direct replacements for factory exhaust systems, meaning no modifications are required for proper fitment.
Included with this catback system is Milltek's OPF/GPF Bypass system kit.
The GPF/OPF on newer BMWs almost acts as a secondary catalyst. In response, Milltek has provided the option to remove this component, similar to a Decat system. This bypass deletes the GPF/OPF, removing it from the exhaust system to better improve performance. - GPF/OPF Bypass software is required on the vehicles ECU in most cases. Includes all hardware required to install.
