GMMG chambered exhaust for sale
I think I'm going to sell my GMMG stainless chambered cat-back for my LS1 to get something cheaper. It's pretty much new with less than 1000 miles on it. If anyone is seriously interested, let me know so I can start looking for another system. $600 and it has the single stainless tips.
