It has quite the bassy drone at 3k rpm, my phone can't seem to pick up the bass though. Doesn't seem to rattle my falling apart headliner as well as other rattles, but it does sound bassy. For me it's livable (use to it) as my other non-mopar vehicles drone just as bad with magnaflow and borla. I'm also missing the cardboard behind the rear seats...maybe it would drone less. Also has 2 6x9 holes for speakers at the back, with no speakers installed. Here's a video of her running at 3k rpm at idle. Also will include a cold start around 750 rpm with a couple of revs in the 2nd video. 3rd video is for sound purposes only, as I'm still trying to get a go pro and mount for the footage. I babied second gear, because I'm still new at shifting a " real car" and did not want to mustang my pride and joy into a street lamp. All 3 videos, car was still at 20/35 advance and not 14/34.
