Exhaust question

[lmeavtitn]

I drive a 2003 Ram 1500 5.7 Hemi Auad Cab Short Box. I was wondering on the stock exhaust, what is the inside and outside diameter of the exhaust before and after the muffler?

Off the cats it is 2.5" pipe. Then those two pipe smash together into a 3" pipe, then its into the muffler and out the back with the same 3" pipe.

So are those dimensions inside or outside measurement

I'm pretty sure its outside. Best way to make sure is with the measuring tape.
