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..
