Knock off GMMG??? Ok who likes the GMMG exhaust? "OOOOOHH I DO, I DO!" Yeah me too. Well I was cruising through a catalog and found these. The one on the left sure looks like the GMMG, but has anyone given this a go? I mean about 400$ and you have a GMMG system lying on the work bench. If anyone cares to know where these are located PM me, and I let you know, non sponsor you see. Some will probably know automatically where these are.

Yup those are the same there was a thread last week on these and yes you could build a chammbered exhaust for a good price but the GMMG is all ready to install in about a hour's time with all the bends all ready done and the whole cat back is stainless steel. Either way you'll end up with a killer sounding exhaust.

I'm gonna make a setup similar to GMMG but with spiral flows sometime. I love the way those things sound. I've drawn up something on how I can use 2 spiral flows in place of the chambered mufflers.

I had a custom "gmmg" type setup built for my 95 gmc sierra. I bought two 18" chambers from sweet-thunder.com and had a local exhaust shop fab it up. Sounds awesome but now my Y pipe is leaking at the header collectors so I need to get that fixed...

p.s. cost me about $450 all said and done with the sweet-thunders, custom exhaust and tips...
