GMMG sounds wicked
Well i got BBK headers with a off road y pipe. The car sounds insane. best sounding exhaust ive ever heard on a car period!! Coming from a flowmaster system on my car to this is no comparison! even my old man who doesnt care for loud exhaust or any of that like it. walks outside everytime i went to take off with it listening to it.
Highly recommend this exhaust for anyone wanting a new exhaust. ill try to post vids on here of how it sounds.
Main reason i posted this is people been asking where to get it and what not.
May need some help uploading vids if someone wants to help out.
THanks

Yes GMMG sounds about as good as it gets for bolt on cat back.

I totally agree, Gary is a nice guy and very easy to deal with. I had mine installed last week and its the best sounding exhaust i've ever heard on an F-Body. I love the sweet rumble at low RPMs and then it just gets insainly loud and deep at WOT. Definitely worth every penny. I'll also be posting some videos as soon as it stops raining/snowing in the midwest....

Also yea the snow is holding me back for getting videos. i just hope they dont salt the roads if it storms. they just finally got washed off
Id love to do true duals but i have always wanted a gmmg so i settled for that.
I purchased mine through GMMG right before they closed. Let me tell ya it was an ordeal to get it. Once installed, it was the best money I had spent on the car. I have had people come up to me at car shows before I even had the car parked wanting to know what I had under the hood. Yes it is loud! The rasp comes right at the Y pipe. I had installed the “CC insert” and it made a huge difference. I know there is a lot of debate about the insert but when you can’t talk to your wife driving down the road you got to do something and this was the cheapest way without cutting up the exhaust. This is video before the CC insert. You can hear the rasp going down the road.

I do have 4.10's and when crusing in 6th gear at 60 65mph its really not any louder than when i had my blowmaster system. Only when you get on it then it really barks.

i dont really hear any "rasp". I just hear the sexiest bolt on exhaust ever. this is stock headers/y.
raspy = loudmouth
You can add my name to the cool kids GMMG club!
I got mine installed last week and I think my car is just naturally quiet, or I got too used to open headers/y-pipe setups.
LTs, 3" ORY now (was like 2.75" POS) and GMMG is maybe just a tad louder than my SLP dual/dual.
I'll get a video today.
