Default GMMG chambered exhaust?

I was thinking about getting the GMMG chambered exhaust, but wonder if it's really worth the swap-out from the SLP Loudmouth I have on now. Does anyone HAVE the GMMG exhaust installed on their rides? If so let me know what you think of it in comparison to the Loudmouth Catback systems.

I have the GMMG and my friend has the LM II. The GMMG sounds MUCH better and throatier, and doesn't have the headache drone of the LM. I love the sound, but it's a little on the loud side with heads/cam and longtubes.

i have had both.

Loudmouth = a MILD bolt on car will sound good. Once you start to modify the car (and please dont say you wont.. YOU WILL lol) you will want to scrap that loudmouth fast!

GMMG = awesome anytime on anything!

It all depends on ur style. Find some one with a gmmg and hear it 4 ur self. But dont get me wrong the gmmg does sound tight. I like them both.

LM is abnoxous when its on a modded car...sounds like *** in my opinion.

GMMG is just pure sex at any stage your car goes through...stock to heads and cam, it will sound sick!!

I also have GMMG.I love my exhaust.It sounds very deep like true duels, not to loud at iduel but sounds mean as hell when revved.I get a lots of compliments about how it sounds even before I got headers.It does cost more but I think it well worth the money.It made my TA sound like a 1960's muscle car.
