Default Gmmg?

A lot of people mention Borla, Corsa. Ive also heard alot about gmmg. How good is Gmmg compared to Borla and Corsa? And does anybody have any dyno results?
Thanks Again

I like the GMMG better over the Borla and the Corsa. Sound is just louder at idles. very nice musclecar sound at WOT. I'd recommend it.

Sorry...no before/after dyno results.

GMMG has a more "classic" sound to it - like a 60s big block. Mine, with long tubes, cam, and no cats sounds like thunder rolling through at idle - it gets lots of compliments.

you won't find a better sounding system for a LS1 car...average gain of 12 to 15 rwhp over stock z28 or trans am exhaust. It's also lighter than the other two systems.

I have a GMMG chambered exhaust system w/below mods and I have yet to hear that anyone dislikes it. I have had the borla system and the SLP dualdual and this one sounds better by far. I would recommend it definateley!

Does it get that nasty rasp between 2000 and 2500 rpms?

I am about to get GMMG in the next few weeks. I hve heard some good clips of it http://www.01pewterz28.cz28.com/vids.html
andmust say, "Forget Borla and especialy Corsa!!!" This isthe best. If it is good enough for the new ZL-1 then it is damn sure good enough for me.
