I love the subaru wrx exhaust notes. That aside, I have mixed feelings about the m2 being a four cylinder. With our 1M/135's comfortably tuned to 350-380whp going to any car tuned below that might not be as enjoyable at this point.
I am strongly considering a m2 as I want to step up in performance/driving enjoyment and I hope that an M tuned 4 cylinder can deliver that.
