We do know that the ARM fit because we have members running them. We know nothing about fitment of the VRSF because they were using a local tester, but no one has heard back from them.

Looking at ARM and VRSF prices, why the huge price premium for the Supersprint downpipes? Maybe because they have been manufactured specifically for the M50i whereas the ARM & VRSF are not M50i model specific and with some fettling they fit the M50i

You guys over the pond don't have the noise regulations we have and so your motors already sound half decent. The Nissan LEAF sounds better that my M50i so we are starting improvements from a disadvantage even though we are supposed to have what BMW are calling an M-Sport Exhaust .

So do I start with just downpipe replacement and should they be catless or sports cats, along with some type of control over the actuator valves flaps or do I also go with resonator delete with X-flow
