Fergie, need to make sure on that. Everything I've seen from Paccar with a 2250 is from turbo to the cans (doc, then dpf, they are v-banded together under passenger side), it exits the can going vertical, then turns a 90° elbow back horizontal pointed back forward under the driver's seat, as it crosses over the driveshaft you'll find the decomposition tube (need to check for the "volcano" that Def will sometime clog up here), then another 90 down into front of the scr (big filter no v-bands, just the straps that hold the sensors to it) out of the scr either vertical or horizontal depending on the exhaust layout. If its got dual stacks it usually comes out of the scr goes to a y (or splitter) then separates to the stacks..

I will double check today but here's what I remember from laying under it the other day. The exhaust coming from the turbo enters the bottom can that runs parallel to the frame. It's about 3.5' long. Exits a 90 going up then another 90 headed back to the front of truck. This small pipe I think is the second tube. It's got a sensor and looks like a Doser. Haven't tracked it down yet but the wire and hose coming from it head over the frame to the general direction of the def tank. This pipe makes a 90 and enters a second can that's runs parallel with frame, same size as first can from what I recollect.

My stubbornness only comes into play when the third party shops first thing they say is to demandate and want you to put on new turbo. All for a small fee of $10k. I'm not stubborn enough to ignore your advice. I've got alot of blind faith in you guys here. Never met anyone but after the reading I've done you guys know your stuff.
