H pipe Vs X pipes Vs True Duals
#11
That's weird cause Dr. Gas seems to think the best place for the crossover is as close to the headers as possible...

X or H will offer more power due to the scavenging effect created from the crossover. In my opinion H & X sound far better than true duals, but I think true duals sound like sh*t. Everyone's opinion is different. X sounds best during driving & wot, H sounds better at idle imo. I run an H now, but if I had to pick again I would have gone with the X.
As far as power production between the X or H, the only way you're going to find out is dyno the car with both setups a couple times. Some people on here will say X is more powerful, some will say H. I've seen dyno tests where both produced more. mm&ff & a few other companies tested & both got mixed answers. in one case the X produces more, in another the H did. Personally I would pick based on sound between the H or X & I wouldn't pick the duals at all due to significantly lower power.

Straight pipe, no cross over will accelerate faster than an incorrectly setup H or X pipe.
It matters where the crossover is put...

bolt a straight piece of pipe to each collector, paint the pipe. where the paint stops burning, put the crossover.

Yeah I have an article on it going over size, backpressure, & velocity aswell as the H or X, but it never went into great detail about best location; it did however show some designs based on what they found with their testing. I personally have done no testing to back up either, just what i've read.

I did not know about it until after i welded my exhaust up, or it totally escaped my feeble mind. im kind of curious on how far off mine is, i might just paint mine for for giggles.
Its only what i have read/been told by a person i trust in the performance world.

For an F150. Did you know Mustang headers fit them trucks. Can be had for pretty much free too.
The H favours smaller cams and lower end performance vs an X which will help with scavenging for big overlap racing cams. Since you have a truck I'd go with an H.

F150 headers are not a prob becuase F150 where offered with 5.0's also..
