Generation III External Engine - Chambered Exhaust

Does anyone have this type? What are the hp increased with it and does it sound good? Where would some on get one?

Sounds good to me, I've had mine for over two years now. The GMMG costs more than some of the others but to me it was worth it.

like ^ said, GMMG is a great chambered setup, though for the cost of the gmmg you could go true duals out the back.

I have enjoyed my GMMG since the day I got it. Wouldn't trade it for any other system. Cost really wasn't a factor for me.

I couldn't have said it better. :)

I also think that there is no other cat-back exhaust system that sounds as good as the gmmg. I would recommend spending the extra money for this system, it is well worth it.

I just did.
Got in on the GP pricing; it arrived today.
Now I have to sit and stare at it until next week.
Damned holidays...

Hehehe...sucks bro. But the wait will be well worth it. Give us your impressions once you have it installed.

For anybody that wants to see some nice photos of the GMMG, I've already got a webpage up and running at my 30 page Firehawk website.
It's Geocities, so if there's a mad rush, it'll shut down for awhile and then open up again.

There will be lots more pics up once I actually take off the SLP Dual/Dual and get the GMMG installed. Dyno Sheets, too.

Dawg One where did you get your head rest done it looks great?

Got them done like 2 years ago from someone who is off the net.
As a matter of fact, without using any names, this person is getting slammed in the Buyer Beware section for an engine sale.
I GAVE him the Firehawk logo to do these and then the guy turned into a be-atch.
Sorry I can't offer more help.
