Hi there, Kyle, are you saying you ordered this system?
Riffraff Diesel: MBRP 3" Aluminized Downpipe
It states in the description:
The down pipe back type system mounts to the short stock down pipe in Powerstroke equipped vehicles and eliminates the catalytic converter. The objective is to provide the absolute lowest exhaust gas temperatures, maximum exhaust flow, torque and horsepower possible. The ideal configuration for off road applications.
So it has me a little confused too, if this is what you ordered.

Yeah, that's what had me confused, from seeing the picture without the flange I thought it looked way to short to go into the junction behind the cat. I guess you are supposed to buy a chunk of straight pipe to join behind the cat somewhere??

If you received two separate boxes, they might have sent a duplicate dp by mistake. Give 'em a call to verify. Make sure you ask for the cat-delete, or to be "legal", ask for the "test pipe" so you can run an open exhaust when you're racing.

Hang on to both until you have 1 installed, there's been more than a few that were made wrong. Mine worked fine but the only catch with mine was a poor union of the collar and upper dp. There was a lip at the bottom that stuck up about a 1/4" just enough to impede flow imo. I just hammered it down with a ball peen.
