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,
-Brian

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.

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.

Not to jack the thread, but anyone have a link to the powersticks they're using after the Y with the GMMG?
I am looking to run GMMG with my current LT's and no cats.

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?

Is the GMMG supposed to slip over the Kooks 3" ORY? My ORY was cut off where it was reduced down and I am trying to put this together and figure out a work around. Even considering buying a new Kooks Catted Y.

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.
