The Martelius R1 Manifold has been Dyno proven to produce more power and significantly more Torque than even the High-end Japanese manifolds costing almost twice as much!! The R1 Manifold features stainless construction, and bolt patterns to suit both 16 valve and 20 valve engines. We recommend this manifold for 210bhp upwards.

The R1 fitment is for all RHD models, and LHD without power steering.

Fits both 16V and 20V cylinder heads. Works best with individual throttle bodies and high cams. Not recommended for street use. Do not fit with power steering.

In this version you have a longer collector that eliminates catalytic converter. There is a 2 bolt flange at the end to suit cat model exhausts bolt-on, as per the first picture.

For engines which are only mildly tuned , we recommend the Group A manifold.

In some 20V conversion cases, a small section may be required to be removed from the right corner of the manifold flange in order to fit with the coolant blanking plate.
