Ok guys, i know alot of you have worked on your cats before.....I have a 2000 dodge ram 5.2....headers, duel flowmasters, stock downpipes, stock y pipe, stock cat.......Its the single in single out cat version. Im wondering what the inlet diamter is and outlet diameter is because im making a test pipe....yes i know about the emissions and envirement crap....I just wanted to see if anyone knew...otherwise ill cut the cat off and see myself.[8D] My guess is 2.5" in 2.25 out? or maybe even 3" in

thanks
