Do you live in a state that requires inspection prior to yearly registration? If so you might have issues not having your muffler. I straight-piped mine (no inspection in ky), but I was able to push the muffler to the rear of the truck just enough to separate it at the connection forward of the muffler. Then I used a couple of worm drive hose clamps to clamp the two side by side.

Riffraff Diesel: MBRP 4" Single Muffler Delete Pipe
OEM piping is 3.5in, so you'll need the collector from any autostore/muffler shop to connect the "delete" pipe. As for noise, you keep the exhaust routed to the back of the truck ,and not dump it under the cab/bed, you wont know a difference, considering ,the turbo itself acts as a muffler

you can do what I did, cut the muffler off and flip the s-pipe up thats before the muffler, then all you need is a straight pipe - no bending required, it lines right up

this is what I did too. A friend gave me his stock exhaust and I cut a piece of it to fill the gap. Eventually went to the 4"
