GMMG: Gods Catback.
HOLY HELL. what a diffeence this made to my car. It has so much more get up and it acceleraes so much smooter, its like a different car. There is virtually no drone at highway speeds, and it is not even that loud on on the inside during an acceleration. The outside is a different story.
The only complaint i have is that the tips that they supplied were about 6" too short. I didn't have this problem with my first set... They looked the same as before. What should i do?
Ill put up a video sometime.

Re: GMMG: Gods Catback.
Round tips. if i put them so that they are as far as they can be out Safely, they come just before the edge of the valance... i certainly dont want to melt that thing

I don't work for them. I just like the system. Couldn't think of a better avatar.

Re: GMMG: Gods Catback.
General Motors Motorsports Group....I think.
But why? When GMPP already exists, why start up with GMMG?
GMMG parent company/entity of GMPP?

Re: GMMG: Gods Catback.
Listening to videos of it.....It's neat, but not "Gods Catback", IMHO.
Wasn't real crazy about the sound. Neat for that 60s feel to the sound, but that's about it. And cost WAY, WAY too much, regardless.

Re: GMMG: Gods Catback.
To each his own but ive yet to hear a gmmg (or any chambered) exhaust on the net sound like it does in real life. Some are pretty close yes, but in person they are so sick. Ls's are pretty damn raspy but the lt's and the gen 1's ive heard sound great.

Re: GMMG: Gods Catback.
Oh definatly, thats a ridiculous price, i put powerstick on my gen 1 motor and it sounds ALOT like an lt1 4th gen. So its definatly cheaper making your own.
You can make a full custom setup including electric cutouts for half the price of a full gmmg kit.

Re: GMMG: Gods Catback.
It's the same price as the Borla. Both are stainless steel. You get free shipping with the GMMG in the US. So that lowers the "real" price when comparing it to others as well.

My X pipe really quieted down my true duals with classic chambered mufflers... until I floor it.
