Looking to add some more power to your M3? If so European M3 headers are a common and effective upgrade. The European header features a less restrictive design, and eliminates the factory cats. You will notice a nice power gain as well as a muscular exhaust roar that isn't overstated. This kit also includes new installation hardware for a easy and leak free install.
This part eliminates the factory converter, therefore is for off-road use only
