Madhammer/ GMMG with LT install help
Madhammer/ GMMG with LT install help Hey guys i need some input on how you went from your y-pipe to your gmmg I-pipe. I have ARH LT's and a high flow y pipe to a stock catback on my car right now. the ARH y-pipe reduces down to 2.75" id to slip over the stock I-pipe. I just received my gmmg from gary at madhammer (excellent experience can't say enough good things about them) and the I-pipe is reduced at the begining to 2.75" id to slip over the stock y-pipe. I'm gonna install it this weekend and wanted some opinions on how you did it so that i could plan on what clamps, etc i need before i tackle the install.
thanks a lot,

Nevermind Installed it yesterday and the ARh y-pipe shrinks down to 2.75" ID and the gmmg/ madhammer i pipe shrinks down to perfectly slip over it. Install went perfect, except for having to drop the rear end 3 " to get exhaust in.
Thanks I can tell i'm quickly gonna fall in love with mine. I only got to start it up and idle it in the driveway cause the roads are still crap from salt/ ash but hopefulle soon we'll get a good rain and a warm day that i can take it out and relly fall in love with it.
Like babbage said, I drove around without a powerstick and it started to get irritating so I brought it to a muffler shop and had them weld it in right after the ORY. Cost me $40 and they took 20 minutes to do it right.
I ran a gmmg for a long time with an ory and loved it. It's actually my favorite setup and will be doing it again. Just try it the way you have it more before you go off spending more money on something you may not need.

Shouldn't have to do that....just jack up the frame of the car and it'll slide right over the axle.
Real nice people to deal with.
Originally I tried to get it from Classic Chambered, but no one answered the phone for like 5 straight days.
Not sure what happened there.
This was like three+ years ago.

Which powerstick did you guys go with, and what needs to be done to fit it? (such as cutting the Y-pipe?) I LOVE my exhaust, minus the rasp between 2000 & 3000 RPM under moderate throttle. I'm open minded to easy fixes that won't cost a ton or require much exhaust modifications.
My neighbors probably wouldn't mind it a tad quieter either.
Does it lower the idle decibels any?

I have a question here (bringing this back from the dead).
Most of the time I see folks with Kooks ORY/Catted Y and the GMMG and the consensus is to run the Catted Y.
Is it different with the ARH Y-Pipe due to the merge? Does that help with the rasp?

Sounds nice and mean after the powerstick. All this and it has a cutout. Sounds like the perfect combo to me. I'll be doing the same exact thing (except with a longer powerstick) to mine once my car is tuned.
