Best solution for me turned out to be a modified OEM exhaust I got from Noelle in Germany that has a wider inner pipe that is more of a straight pipe. Coupled with the DP it is about 50% louder than stock, ZERO drone and NOT obnoxious. VERY nice, throaty, "tuned" sound. It is PERFECT for guys like me who don't want to be that "loud" guy at the light and just like to let out a nice tuned note while driving and to be heard well when WOT (even then not obnoxious. Just a perfect finely tuned powerful M5 sound. It is one people hear and say "wow, that sounds REALLY nice-not "whoa..that's loud!" I think it sounds like what the M6/5 should sound like from the factory.Probably what we all expected.) These who like the E-Race, etc. will NOT like it. Those wanting more "classy mean" and not want to shake the house when you start it will find it to be sweet music to their ears ) Only bad thing is that I may need to sell it in 60 days when the M6 arrives as I don't think it fits the M6! I will get another set though!

I like your idea. I am installing catless DP's with the stock exhaust and will go from there. Decisions, decisions.
