Hello All,
We have recently developed a performance downpipe for F10 N55 enthusiast. The part number is identical to the F10/11 chassis which means that the part will fit on the 640i coupe and convertible. We have made impressive performance gains of 24whp and 36wtq at 3500rpm and fuel efficiency gains during economic driving. The car gains a much more aggressive tone and the turbo spool is audibly more present. View our full release thread HERE.
