BMW E46 E39 Z4 2.5, 2.8, 3.0 Tubular Stainless Exhaust Manifold 01-06, LHD only

This exhaust manifold fits the E46, E39 or Z4 chassis BMWs with any of the M54 6 cylinder engines.

Dual 3-into-1 design for optimum street performance, where the exhaust meets the OEM system the pipes are 2″ ID.

These pipes remove the 2 pre cats that were on the M54 engines.

Estimated power gains from 10 – 30 BHP depending on other supporting mods.

Comes with the gaskets and everything you can see in the pictures. 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. The lambda sensors can be very tight to fit on this manifold and therefore we recommend using CEL cheaters to give the extra space required and also to help prevent the EML from illuminating.

We know this manifold fits LEFT HAND DRIVE vehicle, they can be fitted to right hand drive vehicles with  modifications. Please ask before purchasing if you intend to modify for a RHD car.
