I installed GMMG!!!!!! omg this exhaust is so sweet its nice and deep and has an awesome tone when you get on it i had a hooker cat-back with a cutout before and i didnt like the cutout because of all the vibration so i installed this one and it sounds so good gmmg exhaust is the best cat-back out there took me 45 minutes to install and the tips look killer 
Re: I installed GMMG!!!!!! Congrats on teh GMMG!! It is a very very sweet system. I love mine. I have long tubes with no cats on my car and yes there is some rasp but only when the car is cold, and it is right at 1500-2000 rpms. It is not that bad. Believe me, I was worried about how mine would sound when I did the long tubes with no cats, but honestly it is fine. Oh and with my cam, longtubes, and the GMMG, I get comments from everyone - Harley guys, hot-rodders, everyone. Its pretty cool when a guy running chambered side pipes on a 67 427 vette comes up and says "your car sounds great"
Enjoy the system - it is absolutely worth the money.
By the way - did you get the tips - or are you using something else?

Re: I installed GMMG!!!!!! ClassicCollector...I also get compliments on how my hot rod sounds with the cam and my GMMG! The LT's w/o catz with this exhaust system sounds bad azz IMO!

Re: I installed GMMG!!!!!! I just ordered my gmmg exhaust yesterday and was planning on gutting my cats while I was installing it. Does anyone have a sound clip of gmmg with stock manifolds and cats and one without cats? I would really like to hear the difference in sound. TIA

Re: I installed GMMG!!!!!! It won't sound bad at all with gutted cats. I can vouch for ClassicCollector's car. With his GMMG and cam, he turns every head everywhere he goes.
Right now I've got the Loudmouth, but I'm VERY seriously thinking about swapping the resonator for a chambered section... especially since I don't have the money for the GMMG.

Re: I installed GMMG!!!!!! Yeah...anyone, PLEASE, post clips of the GMMG w/o cats...I'm running SLP LTs, Y, and cats with my GMMG, but I'm considering losing the cats, but I don't want too much rasp and crackle!!
I just installted QTP longtubes, TSP catted ypipe and gmmg! I love the sound! Its quiet inside in the car cruising around town but loud when you get on it. I had a friend drive my car down the road and its definately louder outside the car than inside!
