GMMG Exhaust

[$ickZ06]

Sounds so awesome.. I bought it used and it is one of the best sounding exhausts i have ever heard on a ls1.

[LS1_Disciple]

Definitely agree with that.

Me when I first started mine --->:jawdrop:

I agree, I heard one with and without headers. The one with headers and no cats was a little much. BUt the one without headers was badass!!

[$ickZ06]

yea no cats= rasp

[gdu]

I want headers, true duals with cats and these mufflers!

[LS1_Disciple]

Sweet thunder makes a chambered muffler you can use on true duals.

[Bayou Boy]

I agree with the GMMG being the best sounding exhaust for an LS1 :thumbup:

It's the best when you start it up on a cold morning. It's so damn loud, even on stock manifolds.

How does it sound compared to the SLP loudmouth.?

I had a LM on my 00 T/A. It sounded good but it was a bit raspy. I'm kicking around getting an exhaust for my 01 SS and the GMMG is tops on my list, just haven't seen or heard any local f-bodies w/ this system so I can make a final decision.

No drone on the interior like the loudmouth, Sounds awesome both inside and out, not too loud on the interior but louder on the outside.

Cool, thanks. Sounds like just what I'm looking for. Now, I just have to wait till I have a job and I can order one. :(

As soon as I get the money, the GMMG will be the exhaust I run after my headers. Right now I have a cutout with a 12" bullet right before it, and I think that will be way too loud for my tastes.

Oh, I definitely did the cats...since I can't weld up my old exhaust (which is mild steel) to the Kooks y-pipe, looks like I'll be doing this sooner than I expected. As soon as my next credit card cycle goes, it's on. Can't wait...my exhaust sounds like shit with the huge leak.

Just had my GMMG put on my 02 T/A this morning,sounded so good I put 100 miles just crusin.:D Its not bad at idle but when you hit the go pedal.......................:drive: Plus with the M6 downshifting or holding it in 2nd or 3rd..................:headbang: :cool:

[JAXFLSS]

I love my GMMG. Love it even more with the Kooks LT's. :D

[RallyRed701/2]

[99zee]

Does anyone have some video clips? I know about ls1sounds, but would like to see the video. I have had the B&B for 5 years and have been thinking about the GMMG. Don't know of anyone in my area that has one

[Nova5]
