The M-Perf may even be somewhat more and I agree, not much whp gain, but after market (legal) exhausts aren't renown for serious performance gains. Perhaps a little boost.
Got quote from dealer as follows:
M performance exhaust 328 - $1,748 + tax
M performance front splitter - $641+ tax
Quite a lot higher than BMR is offering.
