H pipe Vs X pipes Vs True Duals

[F 150Cobra]

wich one is better in performance and wich one is the better sounding one


im planning on true duals exiting before the front tires on each side..

I was under the impression that the H pipe just equalizes pressure for smoother flow, and most of what I've seen is less than a 5hp increase. Personally, I can't tell the difference in sound between H pipes and true duals.

Little bit of info...if you do plan on doing an H pipe...throw some paint on the first 3ft of your pipes, and where the paint is burned off...that's the optimal place for the H pipe.

AFIK You want either an H or an X.. X iirc is supposed to "operate" at a higher rpm, also supposed to "give" a more uro sound.

At least thats my understanding, from last time I looked it for my stang..

the small block ford engines tend to like to like h-pipes better than true duals. Also true duals will give you a VERY raspy sound. the H-pipe will give it a more even, smoother sound. i know someone who decided it would be a good idea to put true duals on qa 93 t-bird with a 5.0, and the car fell flat on its face, and i'm sure you would use mufflers where he didn't but it was just loud, raspy, and obnoxous. when he floored it like a big fat ugly dude screaming as loud as he possibly could, where a 5.0 stang with bassani x-pipe and mufflers sounded like Mozart's 9th symphony. An h-pipe with some descent mufflers (i had flowmaster super 40s on my cougar) will souln awesome
