air Intake

I have a 99 F250 build date 8/98 I would like to know the a good intake at a fair price for this motor. I see some brands that only work with 99.5 motors. Also what is a cat back exhaust and will it help performance. Does this mean from the convert all the way back only?

Tymar. IMO the best on the market and by far the least expensive.

Ditto. Get the Tymar air intake system.

A cat back exhaust system replces everything from the catalytic converter back. It should help performance and fuel mileage and give you a better sounding exhaust. If you can, get a turbo back exhaust system, which also replaces the turbo downpipe.

A turbo back system also eliminates the catalytic convertor, so if you're in an area with emissions testing, verify that the cat isn't mandatory.
