A More Quiet GMMG(video clip) I have the GMMG, and while I love the sound, it's gonna be too loud for me when the longtubes go on. I'm thinking of welding a 3" round magnaflow bullet muffler into the I pipe. Do you guys think I'd be crazy for hacking up such an expensive exhaust? I also thought of adding a powerstick, but I think the magnaflow would tone it down a little more. I'd rather keep the GMMG and find a way to knock down the volume a bit, rather than go with a different catback. Have any of you guys put a muffler in the I-pipe of your GMMG?

Well you have lots of options.
You could just run a catted Y pipe, it will help with noise supression and as long as you get good high flowing cats they won't really hamper performance.
A glasspack muffler in the I pipe should help reduce noise also, but it will change the tone of it.
Stainless Works offer a similar exhaust to the GMMG but it uses 3 mufflers as opposed to two. But it is quite pricey. Adding a chambered muffler (from Stainless Works or a Powerstick (these are not stainless steel)) would IMO be better than a glass pack muffler as it should keep the same sort of sound.

LOL! If only I lived in Texas, I'd have a cam and exhaust more to your liking!
Too bad I live in CA where the ricers have given the cops a hard on for loud exhaust, because that means you've modified your car for "streetracing." 
I might go ahead and throw the magnaflow in there, just because I'm crazy like that lol! I guess there's no one here to ask how it would sound, because no ones done anything stupid like this before.......

The thought has crossed my mind, but the GMMG sounds SO good I'd like to keep it if I can make it a little more quiet.

You're crazy man!!! Just get an ORY and a Flowmaster American Thunder 
for your pacesetters. That'll shut it right up! I can't believe how quiet that exhaust is.... after running open headers for a while.
