MBRP exhaust installed
Holy crap what a difference. I've read posts of owners who have installed MBRP systems and said their trucks sounded like jet engines. I thought that description might have been a little over the top. Well I was wrong. Not only does my truck sound like a jet engine, it sounds like a screaming jet engine!

I assume you went with a straight pipe system? From hearing the videos online of the different manufacturer's straight piped systems I can't really hear a difference. They all sound about the same as there really isn't much difference except maybe the location of the bends.

The cat delete is simply a 4" pipe that replace the cat. It helps performance in that its less restrictive. Removing the cat will make your truck much louder so it is possible you will get a ticket. ANd remember that the cat is there for a reason, you will fail an emissions test without it.

my truck is not very loud at all, i do have a muffler, but it doesnt hurt performance at all. it is louder than before when it is WOT, but not unbearable by any means.
yes if you have diesel smog emissions in your state, they will check for the cat, and if it is not there, you will fail. a c-note usually keeps a prying eye away from under the truck however.
the main purpose of cat delete is lower egt's, not really much difference in performance that i can see, but man i have a hard time keeping EGT down now, it must have really been bad with the cat on !! ( i installed my egt gauge and exhaust same day so didnt notice egts before with the cat and the sct)
