The only Dynomax Super Turbos I've had that weren't horribly OEM-quiet are the ones with the same-side inlet/outlet (#37676) that I've used on side-exit exhaust setups - now, THOSE will roar! (The reason being that they only have a U-bend in them, versus an S-pattern of baffles.) I got rid of the Dynomax cat-back I had previously installed on my notch last year, and my only regret is that I didn't quite cinch up the tailpipes on there exactly the way they need to be, but that has no bearing on the sound whatsoever.
I LOVE the sound of my current exhaust, though I wish to heck that I could permanently fix the sagging midsection and misaligned tailpipe problems that detract from the fun. I agree with what's been said, I can't believe nobody else has thrown out rave reviews or even a passing mention of Pypes Violator muffs. Not only do they sound HELLA badass, but I got a smokin' deal on them at WFC9 last year - $80 for a PAIR.
With stock headers, a UPR cat'ed X-pipe, and 2.5" stainless Dynomax tails, they've got a VERY nice burble at idle, a wicked rasp that opens up magically at WOT, and ZERO drone whatsoever - they were somehow actually quieter inside the car at cruise than the Super Turbos that I took off, if you can imagine that.
One of these days, I'll get around to compiling all of the video/sound footage of the different exhaust setups I've had on my notch. I'm still giving serious consideration to overhauling the exhaust yet again this coming spring to replace the UPR piece of crap with a Jeg's off-road X (and keep the UPR turd for strictly smog testing) and throw on another pair of Dynomax #37676 muffs with side-exits...
