Cat delete test pipe.

Cat delete test pipe.
hey guys i was wondering if any of you bought, and installed a 4in. mbrp t-409 stainless cat-back exhaust system on a 05 6.0L. (this is what I currently have on my truck), and later decided to take the Cat off and run some sort of test pipe in its place? any difference in sound/performance/egt/quicker spool up with the cat removed. If any of you did do this where can I get a cat test pipe and bolt it to my stock downpipe and MBRP system without too much trouble?
