Hello team. I posted this a few years ago as I purchased a single side of the m5 exhaust and never got around to putting it on. I stumbled across it again the other day and considered about installing it again. Last I remember my exhaust was a 3inch and the M5 was a 2.5inch which made me reserve about doing it. I am looking for a slightly more aggressive sound is why I wanted the M5 and could never find anything on it and still can't. I have deleted the resonator and midmuffler which sound good but makes me want just a bit more. Anyways wanted to see now a few years later if anyone has tried it or if anyone has feedback on this.
