I am looking to get a little more outta my 05 6.0. I am wanting to put on an aftermarket exhaust and a new air system to let it breathe better. I need some direction please. Is 4 " the way to go
. Does the cat stay or go ?? I am looking for something to get a nice cackle but not too loud in the cab at highway speed. Also probably is a dumb question but where do you go to get these mods done. I've called the local shops in my area ( I live 1.5 hrs from Chicago ) and no one so far can help a brother out
.
I have a 3 stage Superchip in it already.
Thanks for your help.
