Our proven design, this header fits E9, E12, E24, E28, and E34 chassis cars with the M30 engine. Features 1 5/8″ primary tubes and 2″ collectors so it will work well on performance-modified M30 engines.
Fitment: Intended for left-hand-drive cars, will not fit right-hand-drive cars.
Note: The headers are made from 409 stainless steel. To further prevent under hood temperatures, consider ceramic coating.
Note 2: We’ve made these with open collectors and without an 02-bung. A competent shop can either run a custom exhaust or make a connector to the existing exhaust. An 02-sensor bung should be placed shortly after the convergence of the primary tubes for accurate air/fuel ratio readings.
