The mufflex with a spintech I think will be quieter than the GMMG.
GMMG is a great catback for someone with Manifolds with cats. Unless you want to run a resonator in the I-pipe like some people on the board have done.

From my understanding they both have their flaws. The Mufflex with the Spintech and dual tips supposedly has a problem with flow, because of the way the muffler is designed. And on the GMMG, not many people like how it sounds the moment you add LTs w/ an ORY. Problem is you'll find more vids of the GMMG, than you will of the Mufflex. Try to find someone in your area so you can hear it in person, before you settle straight on the GMMG. If I still had the stock style Y pipe set-up, I'd get the mufflex then just add a cut-out in the i.

Just got a set of LPP headers and ORY... I've was wondering what gmmg sounds like with that combo.. Was also thinking about running borla xr1 and dump befor the rear.. Have seen some vids on YouTube with that but wasn't pleased.
holy shiit, where have you been???

I have the Mufflex 4'' system with dual tips and the I like the sound and get alot of complements but the Muffler is heavy and ****! I'm not sure how restrictive it is I plan to dyno cutout open vs closed in the spring.
Here are some inside shots of the muffler

i have the 4" Mufflex w/ Spintech on mine as well. And like SmokedOutZ28 said, it is a heavy beast of a muffler. But with high flow cats, there isn't even a hint of rasp. GMMG is a nice setup but it's also an extra $250 (for the stainless tipped version) over Mufflex's 4" w/ dual out system. the only downside to Mufflex in my opinion is it's not stainless steel. if i could do it again, i would still pick Mufflex

I went with the Mufflex... Heard the GMMG on a car with LT's and an ORY... had some rasp to it. Then I listened to the Mufflex 4" with the same Headers and ORY and there wasnt any Rasp. I just went with the 3.5" system with the Spintech Muffler. it is pretty damn heavy. I had the LM 1 on it and i just wanted to quiet it down and get rid of the Rasp.
When i had my WS6, I had the bassani on it and it was the best sounding exhaust IMO. Deep throaty sound. Unfortunately Bassani only makes a TD system for our cars now. I wanted to buy the same exact thing for my SS. Thanks for all the help guys.
Dark Juggalo.. hope to see you out and about soon as the weather turns a little nicer her in NC. i make my way down to Charlotte quite a bit. But rarely take my SS down. I was down there this past saturday getting a tune done by Mike.
