Most HP IN CATBACK

Also look into the Bassani True dual system. It's rather expensive, but I've seen a dyno graph somewhere on this forum of it producing significantly higher numbers over even a Borla catback. Just my $.02

and would like to see where each muffler stands. Thank you 
. This would help alot.

Might as well toss my 2cents in.. I have GMMG on my car with rest being stock.. When warmd Up.. the inside of my car is Nice and Quiet.. Yet has a nice Tone.. Even at crusing Speeds it is Quiet. Now the Outside.. Yes i have stood on the side of the road and Had the chance to list to my car 1st hand experience It sounds Great. On WOT or When Throwing Revs It just sounds Compplety BAdd ***..You pay for what you get and what should matter most. TOne/Flow
I understand that GMMG is a quality product and sounds great at WOT. Is it worth 322 more than the LMII? I wonder if the Bassani will clear my driveshaft/crossmember loop?
