A set of highly polished front pipes that run underneath the engine rather than along each side, in the same way that was used on the BMW SportBoxer that raced at Le Mans this year.

Fits to the rear section in the OE way, so it can be used with the OE silencer or any silencer that fits onto the OE front pipes.

The pictures on this page are of the version without the catalytic converter, but the homologated version is the same except the cat. is fitted towards the rear of the central pipe in the same place as the OE pipes
