Okay, BBP is coming to the windy city next month, so I want to have a muffler on. On my 2006 Z71, I see 3" center in, dual 3" out that immediately merge back to a single 3" tail. I feel like I read somewhere that only one of those exit pipes is open to the tail (can't find this again... Maybe because I dreamt it or something). Should I be looking at a single in /dual out, or a single center /center, or what?

New muffler or not, you'll dig the BBP tune!

Single in, single out, and delete the merge with a section of straight pipe. One is NOT blocked off however.

That's the direction I was going in my head. It looks like they merge pretty evenly so.... Center /center then? Has anyone else done it like this?
