I have the AA exhaust - great sound but I wanted it a little louder. So I went with an Xpipe with resonators without HFC's(Didn't want the CEL issues). The drone is loud. It's been 2 days- maybe things might settle since I had some things rattle inside the cabin with the vibrations- that was the first day. Today I didn;t have any rattling.
