With cats this exhaust is no doubt one of the best-sounding exhaust setups I've had. I've decided to sell it since I've been running without cats for awhile and don't plan to go back anytime soon. This setup is awesome on stock manifolds and cats, and if I went back to that I would put the GMMG back on. With headers and cats its even deeper and louder which is very .

I would not try the GMMG with headers and no cats however because then the chambered mufflers tend to rasp like crazy in the drone range 2000-2500 rpm, but at least the rasp sounds tuned.


I'm selling this with about 3000 miles on it. I've also polished the system since the pics below so it looks like chrome.

I had the intermediate pipe cut shorter to fit my headers and custom y-pipe, but I could get Nick at Nick's muffler to hook you up with some 3"pipe and the install.

This exhaust is rare and very few people have them. I also bought the optional tips with it and they're welded on.

Brand new it's $850.

I'll sell for $600.

EDIT: GMMG Exhaust $500-SOLD
Optional Tips $100-SOLD

I would only like to sale in Texas since the exhaust won't fit back in the box with the tips welded and I'm not going to separate them.

Here's some video clips of the GMMG on stock exhaust manifolds and stock cats.

Also GMMG has some clips on there site.

Nice clips.

Rarely do you ever see someone selling their GMMG, because it is so worth it. I'm not sure but PhatTA may be interested if he hasn't got a Loudmouth yet. I keep telling him to get one for his heads/cam LS1 car but he refuses.

Good luck selling, although I know you won't have any trouble.

 

Alright, I'm going to separate the exhaust and the tips so if you want either one here's the prices.

GMMG Exhaust:$500

Optional Tips:$100

The tips would look very cool on a T/A.
