I think due to the low lift of the cams and maybe the mild duration, the exhaust isn't so loud. Are you still running the stock turbo? that will be another reason.

50 trim with full 2.5 mandrel. no cat, no muffler. straight out the back.

above 2500 its loud. I'm trying to find a way to make it a little more quiet, but still be able to hear the turbo spooling. it sounds great at like 1500-2000 rpm,
i'm going to find a glasspack to put in the center to try and muffle it a little and see how that sounds.

Yeah, on my 8 valve years ago, tried a 3 inch sidepipe, holy crap, I started it and my whole shop shook, was soooooo loud.

its bearable once its warmed up, but on a cold start, or when you get into boost its fawking loooud!

but... i have been getting great gas mileage since it got loud, cause i realize when im into the throttle more... lol

50 trim t3/t4 dual ball bearing turbo, 3" no cat, with muffler. Nice low grumble until I get on it. Then you hear the turbo wine like crazy. ;)

t3/to4(E wheel in a B housing), 3" downpipe, cat, Sebring Tuning muffler. Also a shaved head and a stock gasket (upped the compression a little).

Low lopey idle that can be heard for a good distance but isn't actually "loud". cruising is quieter than a stock SRT4. WOT is somewhere between a Supra and a leaf blower.
