Sorry - kind of an old post but I see you did not get any replies. Not sure if you have done anything yet. What engine do you have? If it is the 6.0l diesel it is not recommended to add cai if under 500hp as you will not see any benefit and will lose in filtration quality. For exhaust if you go straight pipe brand doesn't really matter. I went with the 4"MBRP with cat delete pipe and am real happy. I clicked on your name and noticed you live in WA state. I live in Monroe, WA and you are welcome to come and listen to mine if you are near by. If so just send me a PM.

Dito above.....Keep the OEM intake,it's great for up to 500hp. and cant be beat on the filtration end. Go with the MBRP 4" with cat delete. You'll be pleased...Eventually get a SCT programmer and some custom tunes.Good Luck ...Steve
