E46 M3 Factory Euro Header Set - (NO LONGER AVAILABLE)

The original Euro headers for the E46 M3 are the original M3 header upgrade. They were the first set of headers we used back in 2001. These eliminate the original US catalytic converters in the stock UE manifold (the Euro cats are under the car in the exhaust center section). With no restriction the Euro headers will gain over 15hp from a stock US M3 (slightly less gain if using sport cats in section 1).

There are a lot of different headers for the E46 M3 but many of them are cheap copies of the true Euro headers. These are the genuine article without the quality issues and fitment nightmares of ultra-cheap imitations. Since these are Genuine BMW parts they are a direct fit to your engine with the proper flanges and routing with no interference with the air pump or other accessories. These can re-use the original exhaust studs on the engine and factory gaskets. New gaskets and hardware are highly recommended (offered separately below). Since these are straight off the Euro M3 they do not have the same port locations for the post-cat O2 sensors or EGT sensor. These can be added by your installer or run special software to run without them.

Since these headers replace the factory US catalytic converters they are sold for race and off-road use only. If your series requires a catalytic converter there are multiple options for sport cats in section 1. Special software will be required to prevent check engine lights and fault codes.
