Dude, the 6.0 powerstroke is the best sounding diesel with an exhaust system. Too bad they are pieces of shit. I had one and blew the head gaskets at 55k miles. Turbo and all injectors had to be replaced at 78k miles. After that I got rid of it, but it was the fastest thing I ever owned. I could hang with a fucking vette, and smoke a Mustang with it.
