aFe Power MACH Force XP Downpipe-back Exhaust (F8X M3/M4)
£2,440.00 – £2,650.00
aFe MACH Force downpipe-back exhaust system for F80 M3 and F82/F83 M4. Constructed from mandrel-bent, fully TIG-welded stainless steel, this exhaust drops from the original dual exhaust format to a single 3″ pipe, dramatically improving the sound of the S55 engine.
This exhaust also removes the secondary catalytic converters for less restriction, and includes the provision for an OE exhaust valve (deletes the right hand valve). Claimed increases of 15hp and 30lb ft by manufacturer, with 9.5kg weight saving. As tested on our own F80 M3 development car.
Engineered and manufactured in California, USA. Available with black or carbon fibre tips.
