Downpipe Question

So I bought the truck about a month has 4" exhaust but still has the stock cat in place. I'm wanting to do a cat delete, but everything i've read says that they'll only fit an aftermarket downpipe. Any ideas???

Oh...the rest of the exhaust is by MBRP and I know they sell a kit with the downpipe that you leave the stock cat in...anyone know how to tell if that might be what's on my truck??

Possibly 08 Mirrors? Can't decide...

You could cut it out, get a piece of 4" pipe and 2 band clamps. One clamp to connect 4" to 4" and the other that has a 3.5" end and steps up to 4".
