Exhaust with no flange at the Cat?

I currently have a 3in Diamond Eye downpipe and cat delete on my 250. The DP bolts to the rest of the exhaust, and necks down quite a bit. Getting a 350 and would like a full 4 inch exhaust after the DP with no flange, just a 3 to 4 inch adapter.

Does the full Diamond Eye system clamp, or bolt together?

Any other recommendations? Thanks!

Thanks, I though it might.

One more question, anyone go from downpipe and cat delete to a full 4 inch system with muffler? I wouldn't mind some more sound, both blat and turbo whistle.
