I read an article that shorties only gave 5 more hp at the most. Not worth the trouble. Our stock manifolds and exhausts breathe pretty good. You will find good gains from the longtubes, but I've heard you need a tune with them, because it changes your A/F ratio.

correct. there is debate over whether or not the hp is because of the necessary tune changes or from the headers, but who cares what its from? u get more hp.
you'll burn ur exhaust valves without a proper retune.
F/A ratio stays the same. Thats from the ford racing tech guys.
I believe the tune is one way to get rid of the O2 sensor codes if you get rid
of the sensor.
