BMW 3-Series E46 Tubular Decat Exhaust Manifold, RHD cars, M54 engines
This exhaust manifold fits the E46 chassis BMWs with the M54 6 cylinder engines as a direct 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.
These manifolds do avoid the steering shaft but are still extremely tight, if your engine mounts are old and worn the manifold might touch; in which case you either need to fit a skinny steering shaft or replace the engine mounts.
Please note some of the E46s have uprated engine mounts as standard – again, you would need to change your mounts in order for this manifold to fit correctly.
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.
