I was hangin out at our local car show and there was a man there with an LS1 Camaro HotRod Magazine edition. I asked him to start it up and my jaw dropped. It sounded unbelievable. It was a GMMG exhaust, but I was wondering what headers are used? He had just picked it up from Berger Chevrolet last week.

 

GMMG sounds good, but gets by true duals.

 

Thats the exhaust with the chambered glass pack looking mufflers right?

 

I havent heard the GMMG Chamberred in person ... everyone says how great it sounds!

 

PJ brought his Camaro up from Florida last year and when he fired it up, we all had to agree that the GMMG is the best sounding exhaust we've heard.

 

Oops, I posted that right before I saw the "duals" thread. Thanks for the link! I'll have to go by there sometime.

 

What does a GMMG exhaust sounds like? V8 burble, clean and crisp, high flowing?

Do they have a website and how much does their exhaust setup cost?

 

somehow i knew this was a GMMG thread. i agree wholeheartedly, in fact id put it up against true duals any day. for example, i have FLP's into the GMMG on my LT1 and theres a guy that also has hookers into true duals on his SC'd LT1 and it was pretty much a 50/50 split on who had the 'better' setup. www.gmmginc.net is their site. cost is $700 shipped unless its on GP, which i think it is, and you get to save like $50 or so. its expensive, but worth it.........you wont be disappointed.

Drove a car with the GMMG setup. Its nice at idle, but it begins to drone in the car at 1900 rpm (85 mph in 6th) that would be a problem for me. Also seems to pick up a resonant frequency in the interior around 2800... somethings not bolted down in that car.

 

thats odd, with my setup i pick up zero drone and no resonance. my buddys 01 WS6 and 00 Z didnt pick up any either......
