99 5.4 Exhaust
here's the question. i have stock manifolds and want to get some headers on it. what are good that aren't too pricy? also from the header, if i get em, how many inches should the pipe be all the way to the back? if i run a 3" pipe all the way to the back, will i gain or lose power? Dual exhaust better or just Y pipe?
thanks, any help is good.
