H-pipe vs X-pipe?
H-pipe vs X-pipe?
(OP)
Is sound quality, and thus marketing, the big difference? Does one create less backpressure than the other at the same flow? Or, does one affect scavenging more than the other?
Good luck,
Latexman

The discussion of its effect is better suited to the acoustics forum; it is located based on acoustic wave behavior in the pipes.
RE: H-pipe vs X-pipe?
I agree. Because of this, one would reason that the H-pipe would put less backpressure on the motor. If this is so, why does an X-pipe consistently have slightly better HP and torque than an H-pipe in the magazines IceStationZebra and I have read? That's a dilema I don't understand.
Good luck,

Question, does anyone think there will be any tuning issues??

Was told it couldnt be done, so
i went and did it!

Again, the sound effects belong to the acoustics forum, but empirical experience has proven over and over, an H-pipe will attenuate many resonances found in twin isolated exhaust systems. If sufficiently large and properly placed, it may show some very slight horsepower advantage, but its OEM use has always been for acoustic control.
For many years, GM preferred to place a second "resonator" muffler at the end of their dual exhaust system, instead of using the H-pipe favored by Ford. Problem was, these resonators, being at the end of the exhaust, seldom warmed sufficiently to vaporize condensate. Thus, they rusted out regularly.

Their removal added a bunch of noise at full throttle.

4:1 single exhaust works fine on a 4 cylinder or even better, 3:1 works great on a 3 cylinder. I'm sure that craze if alive and well in motor cycle circles.

As for the 10% increase. I think way back when this was first introduced someone added the 10% better sound effect and someone else interpreted it to mean 10% hp gain. haha
Never seen any gain or loss in hp.

I have never noticed a power gain or significant difference between H pipe, X pipe or straight dauls -- but I do like the fact that it tends to cut down the noise.
Supposedly there is a very minor scavenging advantage to the X pipe, but that is tough to prove.
