6.0 4" cat back.

I'm considering ordering a cat back exhaust for my 05 250 and everyone I know says mbrp. I live in a quiet subdivision so I don't necessarily want to wake up my neighbors every morning. I'm thinking a 4" cat back to a 5 inch tip and I'm jus looking for opinions from guys who know or have had these setups. I want it to be louder than stock but not annoying. Login | Facebook

i have a 06 f350 and put a diamond eye 4" turbo back from alligator performance on it. no cat and just the flow through muffler. inside the truck noise the same. if you stomp on it with windows down its a little louder but not much. not much performance wise gains either but it was worth the $250

i have a mrbp cat back on my truck, but i got a cat delete pipe.....with just normal driving u cant really tell a difference, just a lot more whistle, but i think thats do to gettin rid of that cat....I still have the muffler, and sounds about the same.......but when i get on it, its louder, and sounds pretty tuff....Id like to have done a 4inch turbo back, but wasnt sure if i was gonna be able to do that myself.....so im now looking for a shop to install, from turbo to the cat back....to get a full exhaust....
