Group Purchase Requests - Gmmg exhaust

How about a GP for this amazing exhaust.

THE BEST decision I ever made (so far) with my car! You will not be disappointed!

I had one on my first ws6 in 2002 and loved it, I agree it's the best sounding exhaust.

yea we need another one. ready to buy here

vengeance racing does group purchases through LS1tech according to their website...

Madhammer.com probably sells them cheaper for what a group purchase would be from the other few companies that have it. $625 shipped without tips, $675 shipped with standard tips.

the madhammer is the same as the gmmg set up? looks like it.

It's exactly the same. Gary-the owner of madhammer, has made every GMMG exhaust from the begining, and still does.
