I am wanting to order a GMMG catback. What did you guys do to order it? I went to GMMGinc.net and went to chambered catback section. It gives the order info, pricing, etc. But there is no place to click on to order one? Do you just send a money order with make, year, model and such to GMMG's address and order that way? Or is there some other way? Thanks a lot!
