I couldnt justify spending that much for a catback. If you want a mean sounding exhaust get hooker cb w/ LT's, if you want loud get a cut out or the loudmouth 1. There are so many cheaper solutions.

Amen! And truth be known those "chambered mufflers" are nothing more than a smaller diameter crimped dynomax bullet. Don't believe me, there was a thread a while back on here that showed the inside of one. Not worth $800 in my book. There are other systems that sound just as good if not better. *end rant* lol

Seems like when there's a GMMG thread around you and I ALWAYS show up lol....

This exhaust doesnt cost $800. And the chambered mufflers are not the same as dynomax bullets, IE. no packing is in them. Guess I justify cost by what I want. When Vengeance can get them they sell them at a reseonable amout with or without the optional tips. The Corsa that is also praised on this site is way more costly.

FYI to all the GMMG haters, Borla and Corsa cost more money and sound no where near as good. It's also stainless steel so it will last much longer than some of the catbacks that 90 percent of F Bod owners have. Stainless steel aint cheap either.

Would you happen to have a vid of your car? I'll keep a Powerstick for less likely hood of Rasp around. I just want it to be deep, and mean while giving me nice down low tq/throttle response. Much appreciated to you all!

Not the BEST vids for sound, but the first is just a roll in first through 3rd shift. The track vid is a comparison of my (close lane) GMMG, LT's, ORY vs. a buddy's LT's, cut-out, Magnaflow. His is MUCH raspier than mine, but his is also cam'd so that may have something to do with it.

Ah, hell; I'll ***** it out some more. This one you can focus on just the sound of the GMMG. My buddies TBSS is so quiet you can hear it a little better. Compared to other LT/ORY set-ups, I think mine is fairly mild.

His name is Gary. Google Madhammer exhaust to get to his website and to get his phone number.
I contacted that company and asked about the exhaust and they want $150 to ship it to Chicago I didn't pay that much to ship my mufflex system. I hope they made a typo on that quote.
