Precision Autowerks is proud to represent GMG Racing's World Class products for the 997 here on the forum! GMG performance has been proven on the race track and GMG's quality is second to none! All GMG exhaust components are made in the USA!

GMG World Challenge Sport Mufflers are made of T304 stainless steel and are fully tig welded, GMG uses its F1 sport muffler design which incorporates Different density packing through the mufflers to absorb unwanted sound and tune out unwanted exhaust frequencies. The system saves over 50% of weigth of the stock system and gives the 3.6 and 3.8 liter engines a tuned sound. An ideal set up for track cars or owners who want a more aggressive sound.

Also available is GMG's high flow sport catalyst with GMG's proprietary cross over center section. Designed as a fully modular system to be fully interchangeable with the all the factory components.

Please contact us at pawparts@gmail.com to order. Bundle pricing available when the mufflers and sport cats are purchased together!

Hey Gus... thanks for sourcing my GMG mufflers... I LOVE THEM!!! I know, I know... I owe you some vids. I meant to do that this weekend, but completely forgot. I'll work on that next weekend... before AND after I install the GMG high flow cats I ordered through you. Hehe

Hi how do the mufflers sound, I have PSE with cargraphic race headers and 200 cell cats already. This was hopefully going to be my last mod for a while.

What did you run before the GMG exhaust.

thanks, Mike

GMG sounds amazing! Here are a couple garage vids I made for reference:

1. GMG Mufflers: 2. GMG Mufflers & high flow cats:
Before that, I had AfterHours Mufflers:
For giggles... here's a vid of no mufflers at all:
I have since sold the car though, and the AH mufflers as well. I am waiting to get the GMG setup returned from the dealer. Once I get them back, I'll post them for sale. :-P

Done!

Ok, so the GMG high flow cats and mufflers were returned to me from the dealership last year, but things were hectic at the time and I forgot to post them. Sorry for the piggyback post, Gus (great vendor, btw!), but I can't start my own thread. At any rate, the exhaust is just taking up space now, so someone help me find them a new & loving home! :-)

how much for the set? is that a 200 cell cat?

JDubya

I'm asking $3k shipped for the cats and mufflers. As for the cats, I'm pretty sure they're 200 cell, but Gus (or GMG) would have to confirm. The cats are made by HJS (http://www.hjsna.com/) and then GMG fabricates the system per order for the vehicle.

JDubya

Mufflers are sold! Cats are still available for $1700 shipped.

JDubya

Cats are sold! Thanks again Gus, for letting use your thread. For what it's worth to everyone else, Gus is a great guy to work with and is very knowledgeable about the products that he sells (amongst other things). All the best!!
