MSW SpecE46 Headers
These are the required headers for all Spec E46 race cars. These start out as S52 tubular headers. Already modified and prepped for installation. Reinforced in critical areas.
Available on backorder
These are the properly modified M52/S52 steel tubular headers as required by the Spec E46 racing class rules.
They are carefully checked for any defects or cracks before undergoing modification for use on the M54B30 engine. To ensure clean welds, each header is completely media blasted to remove years of build up. Then the secondary air ports are welded completely closed so no leaks can occur. Additional welds are made in strategic spots to prevent cracking and leaks, which may occur due to track/race abuse. The mating surfaces are smoothed for optimal seal using stock gaskets (either S52, M52 or M54 may be used.)
Note: whenever possible we attempt to use the stock original studs, unfortunately these are a known weak item when rust or other debris set it. If the stock studs are irreparable, an aftermarket solution must be used instead as the studs are not available from BMW. A simple nut and bolt will suffice. We recommend using a exhaust lock nut (no nylon) and high-temp copper anti-seize to ensure ease of future maintenance.
