302 exhaust

Yes i know another exhaust thread, but none of these seem to answers my questions. I plan on putting longtube headers and di do flowmaster 40 on my 93 f150 5.0 2wd 5 speed, would 2.5 inch dual piping be too big? whats the differences between 2.5 and 2.25 inch piping? Is the ceramic coated headers worth it? Or are these good http://m.summitracing.com/parts/HED-89350/ g also any other opinions would be appreciated and again Im sorry for another exhaust thread...

Nothing worth talking about, and besides what would you rather have better sound or better performance?

you will probably be fine with di do 40 series. I just dont see it being worth paying for two separate mufflers

Don't do the 2.5". The smaller pipes will give you better performance, and I doubt there would be much exhaust sound change between 2.25 and 2.5. I know some guys that like to run even smaller dual pipes because it makes a pretty bad-*** sound.
