OK boys and girls, whats the difference between H and X pipes? Sound, performance, HP, torque?

[foxmustangman]

x pipes give you a bit more flow than h-pipes do.

but x-pipes give your car a more european sound, and h-pipes give it a more muscley sound.

[Daggar]

European sound. lol That's good.

I'll have to get a recording of my European sounding X-pipe. haha

Anyway... the only really significant difference IS sound. The H is a bit deeper and has a cleaner rumble at the low end while the X is more raspy and choppy at the low end.

An H pretty much maintains it's tone throughout the power band but gets louder (of course) while an X-pipe comes alive under power.

For me, it's a trade-off. H pipes sound better down low and X pipes sound better up high.

HP differences between the two are negligable so long as everything else stays the same.

Not all H pipes and X pipes are created equal. Power wise, some are slightly better than others.

BBK told me the HP difference (especially with cats) was insignificant, it was mostly the sound that was different.

Thread posted earlier this month regard the sound:

This pretty much sums it up.

I've been considering going back to an h-pipe. I love the way the x-pipe howls when I get on it but therein lies the problem. You have to bring the rpms up to the 3k range before it really starts to sing (not hard to do with a 4.10). I'm starting to miss that low-speed growl I had with the h-pipe. The x works well for my '92 since I'd rather a more toned down exhaust for my daily. For the weekend warrior though I'm going back to a more aggressive set-up. H-pipe & Flowmasters, I'm coming home!

H-Pipe no cats and Flowmasters. I like'em.

Sounds SWEET man I also have a 347 and put out quite similar numbers to yours. Have you ran it at the track yet?

[GTOreturns]

H pipes ruled10 years ago. X pipes have taken the thrown!

Thanks man. Haven't taken it yet. That was just a baseline dyno with just a few degrees different timing. I'll get a tuner for it and do some more suspension before I hit the track. And hopefully move up to a 150

IMO X and H pipes dont sound too different. i can tell a difference but its nothing huge. there more variance in your headers and mufflers to really tell a difference in just the mid pipe.

i like the h pipe better though lol

Heres My Flow Off Road X-pipe... The NON Euro x-pipe i guess i got riped off.. Should ask Why i dont have the Coffee can Sound...

[foxmustangman]

Not to be rude, but that was the suckiest exhaust video I have ever seen...not the car...the video. Sounds good though. I never said coffee can, I said European, and you could hear it if you revved your engine a little more in the vid.

[5spd GT]

I believe it is tmoss that stated that an H-pipe attributed to more overall power throughout the powerband in a thread sometime last year...

I do not believe there is a real difference between either.

Go based on sound...

I prefer the H...
