4" MBRP turbo back exhaust

So I was tooling around under my truck, and decided I want to delete the CAT. The thing is though, is that the truck already has a 4" MBRP turbo back exhaust, installed by the previous owner. My question is, is there a 4" pip that i can take and replace the current CAT setup?
It looks as though the CAT installed is aftermarket. It goes from 4" diameter, flaring to a smaller (i'm assuming 3.5") diameter as it gets to the downpipe. The downpipe to the CAT pipe is NOT a bolted connection, as I've seen that as an option on a lot of sites. It is just a flaired fit.
So basically, I have a 3.5" downpipe, flaring to the 4" CAT pipe, then 4" the rest of the way out. The muffler was deleted, but I have it kicking around.
I'm thinking I'm gonna have to CUT the cat out...unless someone can point me in another direction.....

no, the downpipe side of the CAT pipe is a flared connection. Not bolted flange like the one in that option
