Well i have a borla CME on my car now. Could possibly swap it for a gmmg setup no CME. Havent really heard a gmmg on a cammed lt1. I like how the borla sounds at idle. and at WOT just curious if the GMMG will be that much quiter? I still want a mean sounding exhaust. Just curious as to peoples takes.

 

I have the 2OTL exhaust on right now till spring. I got a used GMMG system during the winter and I think they sound great. Can't wait to put it on. I have heard these exhausts on our cars before in person and they sound mean. I would like to do the GMMG into the CME on mine

 

the gmmg would be louder then the borla i would believe, my borla had more of a heavier tone
