I am going to be purchasing a '99 F-250 Extended cab 4x4 with 30k miles on it. I already know that I want more power.
I plan on doing the diablo programer, boost, pyro, and tranny gauges. I also want to do the down pipe, and will run a 3.5" or 4" exhaust, is there a brand of downpipe and exhaust that is better than others? I am not going to run a muffler either so the muffler doesn't matter to me.
You should contact Mark Craig at DPPI about his exhaust system. We have it on the wifes 99 F250 Supercab , it's easy to install and the sound is awesome.
