QUESTION, if this has been asked and answered I apologize but I searched and couldn't find it and I'm kind of a newb.
I have a 2012 sierra, 6.2L engine with 3.5in stock exhaust, my stock muffler is off center, driver side in, passenger side out, case is 26 in long. I wanted to do a Corsa cat back but its just to much $ right now, the stock exhaust flows very well so I'm thinking about a Magnaflow round 14161 14' case 3.5 center in- out, has anyone done this? I know its obviously not a direct fit but will it work? I just want to cut the old muffler out and put this in its place. to loud? thank you in advance.

 

Yeah it'll work, and it will certainly be louder than stock. You'll pick up hp too. I love the way my magna flow sounds. I doubt you'll be disappointed.

 

Flo-Pro 2510 (3.5") is a direct fit with pipe size and offsets. Their 2507 is same design but a 3 chamber with 4" in/out that flows more cfm and louder, you would have to flare factory 3.5" tubing to fit 4" in/out.
