Do any sponsors here sell the GMMG where I can use a credit card?

In light of the new TSP Rumbler how does it compare to GMMG?

i wouldnt put the gmmg in the same category as the rumble quality and finish wise. the gmmg is stainless, and the fit and finish is perfect

sound is gonna be a personal preference

and the only place to get the gmmg is, you guessed it, gmmg

I tried to use credit through GMMG but they only except cashiers checks. they said in the near future they would except credit, months.....call them and find out, but im almost possitive they only except cashiers checks.
GMMG is they only one who sells GMMG . Id say buy it, the system is awsome

i got gmmg and there is only one thing i regret, not getting it sooner. save your money up and get this bad boy, i noticed a definate power increase and everyone love the sound of it, at WOT there is nothing else like it, maybe true duals but i love it. got sound clips that will make u forget about the rumbler, and its stainless and fits like a glove, u dont have to worry about rust so thats good

Yeah, it's awesome man. If you don't have the cash, just save it, or draw the money out of your CC account. Just an idea.

if it was another exhaust, you'd have to hold your horses. but since it's gmmg, you need to rush them a cashier's check and get your hands on the system. immediately. just the name GMMG should be enough to scare you... because the sound is big... real big. this exhaust makes you feel like a bigtimer, a jerk, it makes you feel good. the sound will blow the roof off your neighbor's house.

Got my GMMG at the shop while I was in Atlanta/Marietta. Absolutely, no doubt, LOVE it!!!! The sound is awesome, quality was top notch, they put it in for me, as I watched and it went in like a glove. I have a work beater, but I swear I try and find a reason to drive the Camaro! She sounds great, BEST money I have spent on her so far! I would HIGHLY recommend the GMMG, you will love it!
