These kits allow the engine to breathe freely and produce more power, and fitted on 500/550 models with the 5.5 litre V8 M273 engine, it will raise power by up to 25 HP.
In conjunction with the optimised flow obtained by the longer header pipes and sport catalysts (not supplied), exhaust gas back pressure is greatly reduced.
The kit consists of 2 headers with downpipes as advertised. Catalysts and Exhaust system are not included.
You will need to fabricate the rest of the exhaust to fit your original system.
NOTE: This header kit is designed for LHD cars, but can be modified to fit on RHD cars also, and it requires our ECU upgrade for optimal function and performance. The installation requires cutting and welding.
Fitting is from 9 hours.
