Product Description

BMW M42/44 Header/Collector Manifold. A bolt-on, SG cast iron Header/Collector manifold for BMW M42 and M44 engines. ***NOT FOR DIRECT MOUNTING OF TURBO***

Designed with a T3 output flange. Comes with a T3 gasket, 4 nickel-coated studs and 4 copper nuts to bolt down the turbo. Coated with three layers of black VHT paint. To bolt to your head, use an OEM or aftermarket gasket and the OEM studs and nuts.

These are symmetric and reversible! Designed to provide a compact and easy solution to exhaust gas collection. Instead of welding up intricate angle-cut pipes, we suggest using one of these compact headers. Then just weld up your primary turbo inlet pipe and down-pipe. A neat solution which saves time and effort.

The power improvement you get from your build depends on how good your tune is! Figures of 250kW+ are achievable on the M42/44 engines. But… your build must be good quality with a solid tune and enough cooling and lubrication. Do not run excessively high exhaust gas temperatures. Our manifolds are 5mm thick, but physics says that things WILL melt or crack if you go mad with the EGTs.

Above all, this is an easy, bolt-on solution to save time on a build and to get you to the fun faster!

***CHECK FITMENT and clearance of the manifold in your bay by using the dimensioned drawing provided.***

Testing and development was done in an E30 chassis. If your build is a chassis such as an E28 or an E36, it is best to use the provided drawing to measure your engine bay before purchasing the BMW M42/44 Header/Collector Manifold.

If you have any suggestions on how to improve the product, or if you would like a manifold or part that we don’t currently provide, get in touch and let us know!

We can ship bulk castings, unmachined, in quantities of 30 or 60 units per pallet. Shipping cost per unit, as well as price per unit drops significantly. You would skim both flanges and drill/tap all holes yourself to our provided drawings. Send a mail to if you want to chat about bulk supply options.

SHIPPING: We are actively working to reduce shipping costs by adding distributors during 2021. These manifolds are heavy items, and Covid-19 is not helping with shipping rates. If you can arrange your own courier to collect at a cheaper rate, we are more than happy to arrange that with you.

Currently, all items ship from South Africa with delivery between 3-5 working days depending on your country’s customs clearance.
