I would install a complete cat back, not just the muffler. The factory Y pipe is the bigest problem in the stock system. It needs to be replaced. Complete cat back systems are designed from the front to the back to perform as a system.

Y-Pipe is quite restrictive

I would concur with SCR. After having recently installed the Gibson SS single, cat back...I had a chance to inspect the OEM Y-pipe and *that* is where the restriction is. Basically the actual tubing itself doesn't appear to be any larger in diameter, but the Y-pipe is signicantly less restrictive. And with the wide offset of the tubing going into and out of the OEM muffler (read: the Gibson is probably 10-12" wide and the OEM is 14-16" wide, so the inlet/exit holes would not line up with an aftermarket muffler...as most of them would be designed to be used with their respective tubing, etc. I can see where you are coming from and might agree had I not first hand experience on Saturday. $525 delivered baby! You might be able to get it lower, but I didn't shop mine too hard. $500 plus $25 shipping from SoCal.
:noworries
On an unrelated note, at install I reset the ECU per clubtitan.com instructions and it still seems like it just became more responsive across the mid-range now that I have about 250 miles or so on the new system. Volant is on the truck for delivery tomorrow...so my mods will be complete, for now. LOL!

Glad we could help spend YOUR money! :thumbup: Always a pleasure. But as a relative (< 1 month) newbie here, I am very pleased with all the wealth of information available herein. Nothing like being an INFORMED consumer, IMHO.

Good luck!
