Video: Exhaust X-Pipes vs. H-Pipes, Part 2

If you missed it, Part 1 of the X-pipes vs. H-pipes Summit Racing Quick Flicks video series focused on the basic differences between the two designs and how to choose between them. It taught you about exhaust scavenging and how it affects your exhaust performance.

In Part 2, a member of Summit Racing‘s tech department answers some frequently asked questions regarding X-pipes and H-pipes for people trying to decide which to choose for their vehicle.

Some of those questions include:

Which is better for my vehicle?

Which exhaust design will most affect my vehicle’s sound?

Which crossover pipe will best fit my car?

    Hello, I have a 1984 f150 standard cab short bed, 300 4.9l inline 6 with an offenhauser dp intake, hedmann dual collector, aftermarket ceramic coated headers with insulcoat on the inside, Holley 390 1460 series electric choke 4 barrel carb. Homemade cold air kit coming out beside my radiator mounts with a spectre filter and 4 inch tube directly to the plenum on top of the carb. Doesn’t ever run much above 2600 rpms. X pipe or H pipe? I basically just want my engine to perform to its max and I’m not sure if my engine produces enough back pressure to warrant a crossover pipe.

  2. i have an anemic 93 ranger3.0 i plan on building my own dual exhaust to possibly increase fuel mileage and dare i say horsepower seems to me a crossover pipe would be better than just strait pipes and mufflers my other wonder it would a single muffler dual in dual out be any benefit i am not after a loud droning sound just efficiency and a sportier sound
    what are your thoughts

      Brian, should you decide to use one dual in/out muffler it would serve dual purpose for you. You would only be buying/installing one muffler and it would act as your cross over (H-pipe) pipe as well.

  3. OnAllCylinders says:

    On a small cubic inch motor running no higher than that, an H pipe will be all that is necessary.

  4. The first x-pipe vs h-pipe video seemed clear and concise and truly showed the difference between the two.
    The second video seemed pointless beyond showing the cut-aways as it did not really show any difference and it reeked HEAVILY of back-peddling to not upset h-pipe manufactures.
    First video: x-pipe scavenges better than h, but doesn’t always fit.
    Second video: They’re the same!!! And x-pipes will make your American muscle car euro sounding.

  5. Hi,
    I have a 1980 Corvette L48 modified with a 650 Speed Demon double pumper, 3.73 gears, long tube headers. Set up produces approx. 400 hp. .Do you suggest 2.5 or 2.25 pipes for back pressure and with H or X pipe.
    Engine has rev.limiter at 6000rpm.

    Thank you
