Since there are not a lot of quality E60 M5 headers available on the market, and we needed a set for a customer’s car, we decided to craft our own! since both the E60 M5 and M6 utilize BMW’s S85 V10 engine, the exhaust headers are identical so our system fits both cars. Our goal in making these E60 M5 headers was to create an affordable yet high-quality header, that increased performance and unleashed the full sound from these high-revving V10 beasts. To do this we actually utilized the original exhaust manifold since it features equal-length runners from the factory, and removed the restrictions, which are the biggest performance restriction in these cars. Due to the higher flow capability, Our headers in combination with our custom tune added 40 wheel HP.

We refinished and polished the manifold, and replaced the cat with TIG welded 304 stainless steel 3″ piping. By using the OEM manifold we can ensure they fit stock measurements allowing the use of either the OEM exhaust or an aftermarket system. These headers can be ceramic coated for an additional cost.
