Home made GMMG?????
Home made GMMG????? Does anyone still have the home made GMMG thread bookmarked or saved? I used the search but it doesnt pull anything. I was curious if anyone has tried it yet.
I had made a post about making one using bullets where the chambered exhaust is, but got no replys...

But yea all it is crushed piping, not to hard to replicate.

Im wanting to ditch my cutout and hooker and maybe fab up an exhaust like the GMMG. It would be less weight and a better sound. Summit racing carries these for $117 a piece and a local exhaust shop could fab the whole thing for around $100 so It would be way cheaper. What would be the difference in sound from the GMMG if I were to use these and route the piping just like the GMMG? I still plan on keeping my CME also...

I also found these, cost a little more but Ive read a couple times now that they supply the mufflers for GMMG (just what Ive read)! Does anybody know what the inlet/outlet size is? Im guessing 2 1/4 or 2 1/2in...

The GMMG exhaust is a tuned exhaust for sound and performance. They actually tried these things on the dyno before they were satisfied with their product. You will be lucky to duplicate it. A lot of time and money was spent making the GMMG exhaust to make it the way it is. The guys at GMMG ran their cars on the dyno with open headers and then full exhaust with the GMMG cat back, and they only lost 3 rear wheel horsepower on a 500+ horsepower car.
Good luck in your efforts, but I would just spend the money on the true GMMG since they did all the research to make such a good product.
