BMW E46 2.5, 2.8, 3.0 Tubular Stainless Exhaust Manifold 01-06, RHD only B Grade

******  These manifolds were manufactured incorrectly and some of them will touch the steering shaft or the engine mount or sometimes both. Clearance can be made here either by denting the tube or by cutting and welding the tube. Others do not align perfectly where the manifold meets the exhaust.  ****** This exhaust manifold fits the E46 chassis BMWs with the M54 6 cylinder engines as adirect bolt-on part. For the earlier cars with the M52 engine you might need to make some adjustments where the manifold meets the exhaust or change your current exhaust to one from a car with the M54 engine. Fitting this removes the catalytic converters that are usually found in the manifolds, because of this you will need to either use CEL cheaters or have the car remapped to prevent the light from illuminating on the dash. Dual 3-into-1 design for optimum street performance, where the exhaust meets the OEM system the pipes are 2″ ID. Estimated power gains from 10 – 30 BHP depending on other supporting mods. We have a picture of the manifold wrapped with exhaust heat wrap, wrapping the manifold helps to keep under bonnet temps down and also can protect the manifold from thermal shock. The whole manifold has been TIG welded so the chances of this ever failing are virtually zero.
