https://ls1tech.com/forums/sponsor-sales-specials/286369-gmmg-kicks-another-gp.html thats where you can get the GP.. but like SS346LS1 said, they are still really really expensive and you would benefit a lot more by a true dual setup. a lot of people later down the road end up taking off their catback for a true dual setup (ive even been thinking of it).. good luck!
Also, the GMMG really only sounds good with stock manifolds and y-pipe. Once you go headers and ORY, it gets really loud and looses the mellow sound that most people like.
I had it with MAC headers and the sound was obnoxious.

the gmmg is hands down the best sounding catback, its no more expensive then any other quality system, around 700, systems cheaper then that arent worth the loot unless they are stainless. There is a group purchase going on right now, get into that for the best pricing

And IIRC, didn't he switch for more reasons than sound? But the topic is about GMMG so I'll stop there...
