Gibson Sft Muffler Part #?

[anthony2558]

Hi I have a 2008 GMC Sierra 5.3L CC short bed. Currently I have from the cat back a straight pipe that exits infront of the pass side rear tire. Looking to put in a Gibson SFT muffler to dampen the sound a little. I was wondering if anyone has done this and could tell me a part number to look for, muffler length, wide? I figure its gonna be center in/out not to sure of diam size. Its been a long time since Ive looked under the truck to remember this stuff. Any help would be appr. Thanks, Anthony.

I found a list of part numbers. What is the stock diam size of the exhaust?

Just give Gibson a call. Bought a catback from them this spring and they were great to work with. They even called a couple months later to ask how I liked it and if install went smoothly. Great customer service.
