To X pipe or to H pipe

[tallpaul]

that is the question. What are the benefits of each? I am N/A and am getting some exhaust work done soon. Which of these is best?

As I understand it an H-pipe will give you more sound and an X-pipe is more free flowing and better for power adding.

[71cyclone]

The X pype improves botom end performance and quiets the exhaust little..I got the Stainless magnaflo X pype with 2.1/2 " pypes to the mufflers [stock] .the system flows much better than the factory H pipe

[Krytin]

Actually H pipes are more for low end torque. X pipes will develop more peak hp but in NA trim you will only see a few hp more at peak with some loss of low end torque. I

If you are running serious quarter mile runs you will need the X plpe

If you just run stop light to stop light you might do better with the H pipe.

[Marauderjack]

"H" Pipe sounds deeper and more "Old School" while the "X" Pipe is more "ZIPPY" sounding and higher pitch but makes a few more HP at high RPM's!!:cool:

I went with the "H" after having the "X" and like the "H" sound much better!!:beer:

My $0.02 FWIW!!;)

[Blackened300a]

I'm not a fan of the sound of a X pipe so I went custom H pipe. I also haven't seen any hard proof that the X pipe makes more power then a H.

Muffled X FTW, no rasp...

I was just going to say that!

CarCraft did dyno testing on an N/A Mustang, copmaring X vs H

Heres what they got.

Alright. Maybe ill be heading to my exhaust shop come spring and have a X insert welded in.

Wow thats a big difference for n/a?

[STEPS]

to me the sound is very important I don't like the sound of the X pipe just my $.02

If you get a regular x pipe you may not like the sound.

What I have and suggest is this:

X-pipe on mine!

Came with the KOOKS complete kit!

And as far as sound........ You be the judge. :D

Most of you know what my car sounds like. I love it! :rock:

[Mr. Man]

I know I asked this question years ago but my sieve for a brain has forgotten the answer so here goes, Why have any cross over pipe at all? Why not have a true independent duel set-up?

[breeze]

Doom the video of us goin thru the tunnel is a X vs H pipe if u try pay attention

Dyno means zero in real world.

My cuts outs open on the dyno bumped me an additional 13 RWHP and 11 RWTQ. Two identical back to back runs yielded me a 12.13 & 12.15 both at 111, both identical RT's and 60'. Your video even pointed this out.

To keep it fair however, my car was never tuned for any of my exhaust, just AFR checked. Who knows what she would do with a tune that wasn't four years old and outdated. BOOM is my thoughts..

Have you considered a Mac Pro Chamber? Kinda best of both the H and X pipes.

The off-road model for the Mustang works great with a set of high flow cats, the extra length added by the cats gives you the clearance needed for the crossmember location on a Marauder.

You're running Cobra manifolds right?

[StainlessWorks]

X-Pipe will make more power as stated over the H-Pipe, the sound is different due to exhaust restriction, the H-pipe being slightly more restrictive offers a deeper tone (resistance). H-pipe is a simple design that was easy to make in your backyard, basically drill a hole on each of the pipes and weld a crossover tube. The X-pipe requires a bit more to manufacture and due to design is least restrictive and makes more power!!

Why have a crossover pipe at all?

[stevengerard]

Listen to the video above from Summit, it explains it well, not only does it equalize pulses, it also helps draw out exhaust gasses making for a "cleaner" chamber for a better burn next cycle

[tbone]

I think I'm going to put SS Magnaflows on my Stainless Works system. While it sounds great, I still prefer the Magnaflows.

[Vortech347]

Correct.

Where they pretty easy to install?

Not too bad. Mo's did the installation, looked like it was pretty straightforward.

Yes - more peak power - hp & torque, but sometimes it's important to look at the whole curve produced on the dyno. If you're not reving to and shifting at the peaks all of the time it may not be doing you much good.
X pipes do not produce more power over the entire rpm range over an H pipe.

[na svt]

I've had this discussion with Burns Stainless and SPD, they both recommended a correctly made H for power. The problem is that off-the-shelf Hs, and for that matter the Xs also, the crossover isn't always where it's needed. Each combo requires a different placement. I would expect those made by companies like Kooks or Stainless Works to be closer to optimum than those made by companies like MAC, BBK and the other cookie cutter places.

Any crossover (X or H) is better than a dual setup. I've dyno tested the difference, same day, same dyno. The X made 15 more rwhp. This was a 460rwhp n/a 4.6, but the fact remains that it made more power. Gains on a Marauder would be far less. BTW, this was a complete stainless works setup on an NMRA Pure Street car. Here's a pic of the X:

I managed to get my X pipe installed almost exactly (within 1/2") where the Factory H was so I think it's ideal.
