Just wondering if one is better than the other and why.
4.6 2008 GT would be the application as I have now a set of cat back Flowmaster 40s H pipe

H pipe give your more torque and deeper sound like American muscle cars that's why I prefer h pipes

 

[Everett]

Well they honest truth is find what sounds best to you. The power differences are negligeable. Buy what sounds best and don't go too loud. Gets old quick. Jmo

This is not new stuff , Bottom line is H-pipe is for Drag Racing, X-pipe for road racing. That is how they were developed back in the 60's. It was about balancing the exhaust for better torque, and even back pressure. They made a big difference with Carb motors back then along with extend collector pipes

Ok, but does that still apply to the 2005+ models where there is no carb and cars have had 30-40 years to evolve?

Basics still apply, but not everything can be measured! It can be heard. And it is your choice. I went with x-pipe. 80% street, 10% road race, 10% drag, thats my use. My street driving is mostly highway and it runs great and fuel mileage is also great, even with all the mods. If i were 40% drag i would have used the H-pipe, If you like the lopie cam sound use h-pipe. The more mods you install the more you will hear.

Cars can put out the same HP, setup is the key to usage.

Well, not too sure about hp gains when comparing h pipes and x pipes on the 3v 4.6L's, but the sound difference is pretty straight forward.

The h-pipe will give you a deeper tone, especially at idle and during acceleration.

The x-pipe will give off a raspy tone when revving and during acceleration.

Both sound good imo on the v8's. The v6's really should stay away from x-pipes.

Well, thanks for the breakdown. I've been looking and wondering what is best for a good deep rumble at idle and during acceleration, and now I see it's the H-pipe that I'm looking for! Thanks Sonicpony!!!

I run an X pipe, and I couldn't tell the difference from the original H pipe...

Is it an offroad x?

 

[Beav]

It is the Ford Racing X-pipe... with the muffler that comes with the FRPP...

Ford Racing M-5251-R Ford Racing Mustang GT X-Pipe

 

[Stang23]

Do those make the car any louder? And did you feel any gains from it?

 

[Beav]

I might have got a little more power, but how can you feel 5 horsepower? And the Ford Racing mufflers that I have aren't very loud, so the X pipe didn't make it any louder, that I could tell.

One thing I can tell you, and this may sound weird, but I have had several women ask me what exhaust I run on the 05 GT because they love the way it sounds; the last time was on Sunday... . It does have a nice sound, but it certainly isn't loud. I think my 05 Mustang has the same tune and exhaust that you find on a Shelby Mustang GT.
