Thanks for the bump Nick.

In case anyone is wondering ... I just climbed out from under the truck with a string and a tape measure.

Measuring the pipe with the tape was worthless. It it almost all bend and the only good straight potion is where the driverside pipe crosses under the trans. pan and the pipe is crimped there! I'll break here for a momentary rant. WTF. There seem like plenty of room too me for the pipe to cross under without being flattened onthe top. What Chrysler was thinking here is a mystery to me. It would seem to me that with the extra bends and the flattened pipe that the driverside gas preasure would be fundimentally higher as a result of more restrictive piping . That can't be good. I repeat ... WTF Chrysler. Back on topic now. In any case, I wrapped a peice of string around a straight (uncrimped) section to get the circumference and did the math to get 2.47" diameter. That must be 2.5" and my measurement is just slightly off.

So my next question is ... if I pick up a 2.5"X3" high flow Y-pipe, how difficult is it going to be for the muffler shop guys to install? I mean there is not a lot of space between the Cat and the Y-pipe on the passenger side and almost all of it is already bent. Is installation going to nessesitate replacing the pipe from the Cat back to the Y? Also does it seem reasonable to ask them to cut out the flat section under the trans. pan and have the replaced with a round piece as well. Is there any reason for that bit to be flat aside from clearance? My truck is not 4X4 and doesn't go off road aside from mild dirt roads when camping so I'm not real worried about bottoming out.

In any case ... help.
