Gmmg Exhaust

I had it with MAC headers and the sound was obnoxious.

i have it with Kooks LT's and catted Y. It s a daily driver and I love it. The tone is beautiful. I've taken it on 4,5,6 hour drives and its perfect. no headache. Youll love it stock or not

I personally think the GMMG is the best sounding, followed by the B&B Tri-Flow.
Too bad you dont find many of those in the FS forums like you do Lids and Mafs

Ive had my GMMG for 3 months and i still wet my pants when i fire it up and give it a little juice. Id rather spend 700 on GMMG than 700 or 800 on corsa or something else. One of the biggest things u are paying for is the GMMG name. I cant wait until i get my lts and catted y. If i had it to do all aover again i would still get GMMG. Best sounding exhaust on an fbody and the best guys in the world to deal with.

AS LONG AS YOU LEAVE THE CATS ON THOUGH! 
Without cats, it does get kinda raspy in the mid rpms and doesn't quite have that "quality" sound it used to have. But it's a non-issue if you leave the cats on there. And personally, I like the GMMG & header/cat combo even better than a true dual set-up...There is a reason why I have it on both my LT1 & LS1 w/ headers...

But I think you'll be happy.

And IIRC, didn't he switch for more reasons than sound? But the topic is about GMMG so I'll stop there...

Someone please show me where you can get a Long tube/true dual setup with something other than bullets for under $700. Only way i would put duals on is if they ran all the way out the back. Good luck doing that with headers for under $700, good luck doin that without them. Ill stick with my gmmg thanks
