Please let me know
Thank you.

I ran it.
Loud as hell. Just about any TP will hiss, regardless of exhaust. Moderate to heavy rasp on downshifts and WOT which is mostly drowned out by the exhaust itself. Drone wasn't really an issue cruising, but would manifest @ approx 2500-3500rpm depending on engine load. Sounded pretty awesome but almost made an old lady wreck on a 4/3 downshift and decided to be responsible and sell it.
If you're into loud exhausts and can tolerate moderate rasp, go for it.
