I am about the upgrade the exhaust on my dad's truck (1999 F-350 Powerstroke) to a 4" pipe. I'm am having a time tying to figure out what muffler do I wanna run on it so that it'll please him and me. Any suggestions
You might not want to go to a 4" pipe. I've heard that by doing that, u lose back pressure thus reducing HP. You might want to just have straight pipes put on it with some type of glass pack. But make sure to take the Cats. off it u don't have any emmision laws, or less strict ones. I'm not totaly positive about the 4" pipe, but seems to me i heard somewhere that the added space for exhasut to escape reduces back pressure and screws with your engine. And that isn't a good thing

Who told you that? The turbo provides all the backpressure nessicary, so in theory a 6 inch exhaust wouldn't hurt anything at all.

A cherry bomb is a glass pack

This is the 99.5 diesel, it has the cat delete pipe straight from the factory.

Naw, the 4" pipe don't hurt anything.
I'm just wondering what muffler would sound good on the diesel and still satisfy my dad on the noisee department. Any suggestions?
