Often referred to as the "Rally" header, this Genuine BMW header shares the same BMW part number as the Euro EVO II / 2.3 Group A Header (making them one in the same). We have used and recomended this for over 10 years now as the header that gives you the best horsepower across the rpm range - on both 2.3 and 2.5 liter motors.It has a stainless steel 2 piece design and its outlet matches the tubing diameter both the stock 2.3 and 2.5 liter exhaust. As this is a Euro / Racing piece, it does NOT have an O2 sensor port, but one can be added with modifcations to the header. If your application requries an oxygen sensor, we'd be happy to have one of our professional technicians make this modification for an additional fee, simply select your option below. We also recommend getting new gaskets, as well as adding our S14 exhaust manifold stud & nut kit, to replace your old, rusty, weak studs. You'll thank us later! Please make your selections below.(left-hand drive models only)
