Default Got the GMMG on!
So after picking up a used GMMG for Christmas I got it on this week. Here are some pics of a very dirty car after it got installed and then some videos after I got her cleaned up. The setup is LPP LT's and ORY, Magnaflow high flow cat, and then the GMMG to the CME.

Thanks guys. I'm really happy with it and it was worth the money for sure because I picked it up used for only $200. Even with the Magnaflow cat ($75) and having the I-pipe and bends made along with the install ($200) it was still almost $300 less than new.

Nice sounds good as hell. Hey Greg did you buy those CME tips from me or was I chatting with you about something else? I remember your name but I can't remember from what.

Just went to a gmmg with high flow cats and a dynomax bullet in the I-pipe and couldn't be happier. No rasp, very little drone on the highway and sounds great at all rpms.

We were chatting about the whole setup and if the stock 90 deg bends worked but I've had my CME, it was on option on my car.

Mine has a tiny amount of rasp at certain rpms but nothing bad at all, it's got less than the dual/dual catback with no cat. But mine does have some drone from like 60-70. I've learned to deal with it cause it sounds great otherwise.

I think the combination of my cats and the bullet in the I-Pipe killed ALL the rasp and the only drone is on moderate acceleration when cruising. Just keeping a steady rpm on the highway there's no drone at all.

That's the way to get rid of it.

Sounds great man. I love my GMMG. As soon as my TSP 1 7/8's I ordered a month ago get here I'm throwing those in with the TSP ORY.

Yeah I still love it, we'll see just how much after I have to drive it a little over 3 hrs back down to school with the slight drone that I've got haha. But your setup should sound pretty good, let me know if you have any rasp.

Coming back to this dead thread. The TSP LT's I got were deffective so I ended up throwing some Pacesetters on with the TSP ory and it sounds PHENOMENAL. NO rasp despite all I've read and it sounds 1000x better than the GMMG w/ stock manifolds and cats.
