VRSF N54 Turbo Outlet Chargepipe 335i Clamp/CouplerVRSF N54 Turbo Outlet Chargepipe BMW 335i (Clamp Coupler) The OEM turbo outlet on the N54 necks down to less than 1" at the merge collector. That is a serious bottleneck on both stock and aftermarket turbos, and it is costing you power. The VRSF 2" high flow aluminium turbo outlet removes that restriction, frees up to 30whp, and allows the turbos to work more efficiently which reduces overall wear. Bolt on fitment, no additional components required.
