I have the GMMG and love it!! But on the other hand I have Pacesetter LTs, and the TSP ORY and from like 2400rpm-3400rpm it does have some rasp to it and is LOUD as hell!!!! But I have heard you can get a catted Y-pipe and get rid of most of the rasp. But I have had a couple of exhausts and have heard ALL ot the most popular exhaust on local cars and I just REALLY love the tone of the GMMG. But it comes to personal taste. Check out LS1 sounds and compare clips or even find some locals and compare. Nothing like hearing it in person!!! Good luck!

I've heard a GMMG on a 650hp procharged LS1, but thats kind of hard to compare to how a cam only ls1 will sound with it
I've been down the LT ORY and Loudmouth road on my previous car which was horrible. I swithced a to a Hooker which sounded good it just wasn't loud enough and it didn't Bling enough. I've spent countless hours on ls1sounds, but I just wanted to get a personal opinion. The GMMG did sound alittle raspy there though.
I would run duals, but this is my DD and duals drone alittle to much for me. I do love the sound of them though.

I have the GMMG with a catted-y pipe and kooks headers. It was a little raspy from 2500-2800. I actually found that some of my rasp was being caused by the i-pipe hitting the passenger floorboard. I wrapped/padded it with silicone and it took almost all of it out. The real source of the rasp is going to be the y-pipe. Get a custom one made that actually has a 45deg merge between the two pipes. Or get a standard y and grind/smooth the inside of the merge. That's been reported multiple times to alleviate some of the rasp.
You know you've met a real car afficionado when they see the mufflers and tell you it looks just like a first gen camaro.
