I have heard them paired with an x-pipe which also sounds amazing - but without having PSE and an exhaust button, I found it a bit loud for daily duties in quiet neighborhoods when I go to visit clients.

I have a few other cars, mostly AMG's. The V8 note and rumble from those with the performance exhaust is enough to keep me happy when I want to make some noise
