I know I know! "use the search function", and I did. But I'm not finding what I need. What is the stock exhaust size? I have a 2006 FX4 SC and looking to upgrade to a little more sound this fall.

Typically the inlet/outlets on the muffler match the piping size. From the back of the header to the exhaust tip, is it 2 1/4, 2 1/5, or 3in piping?

Reason I'm asking is, I want to replace the stock muffler with something else this fall. And kind of want to know what inlet/outlet size mufflers to look at. I also have a nice pair of 2.5in, resonated 304 SS tips from Silverline Racing that I'd like to use on this truck if the sizes match up.

Awesome. Thank you. Was hoping I didn't have to scrap those tips. Thinking of going with a classic chambered muffler. Had those on my mustang at one time and they sounded pretty aggressive.
