quick question, h-pipe and true duals?
im gonna dual my truck out, on my 93 f-150 ext cab, 302 v8 and im gonna run 3" pipe to 10-18" glass packs then run a short piece of 2.5" pipe to the tip and 45' it in front of both rear tires, i heard somethin about a h-pipe needed for true duals, is that true??

as i said before, i do not know the firing order...but you might wanna go with 2.5" pipe instead of that 3" pipe. your low end is going to hurt with such little backpressure in your exhaust. on my mustang, when i went from the stock 2" single exhaust to the true duals with flowmaster 40's and 2.25" pipe, i noticed a decrease in the low end power.

You don't need an X-pipe or an h-pipe unless you have a high horsepower engine. Won't do a thing for you. True duals? What headers will you use? On a stock 302... 2 1/4" is plenty big. 3" will kill your low end power.
