x-pipe vs. h-pipe , best sound
 

what do you think has the best sound, x-pipe or h-pipe

It all depends on what you like my car is pretty damn quite after my X-pipe install.

Sound
 

They both have something to offer,lot of variables here.

I have a Mac H-pipe with converters,and 2 chamber flowmasters with full tailpipes,and it sure does not sound like I have converters on it.

An X-pipe does not sound any different at lower rpm's but get it up in the rev range and it takes on a real surreal sound,they sound awesome upstairs on the upper end of the tach,and build a little more high rpm power,reason they work on 4V 4.6 Cobras so well.

In the end it is all a matter of personal taste and sound you like,only thing I can tell you,get out and listen to some cars with both on them,with cats,and without cats on them.

I love the way my h-pipe sounds

but sound is going to be a little diff. depending on the cat back ,cats or no cats and the brand of x or h pipes

Like everyone else says, it is all in what you like to hear. If you don't like loud *** exhaust, get a x pipe. If you want your car as loud as it can possibly be, get an h pipe. I have an o/r H pipe with 2 chamber flows. No tailpipes, just turndowns. It ain't loud enough for me. But I love the sound of the flows, so I am leaving it like it is. You can feel the exhaust beating off of the road in the seats.

The difference between the two is that the h is louder, but the x makes more power. Not that much difference in power though. A big difference in sound.

Flowmaster sound good with an h-pipe, x-pipe sound good with mufflers like borla, bassani, dynomax, or turbo mufflers, not saying you cant mix match, i heard 1 chbrs flows with an x-pipe and longtubes, it made my car sound like a wimp, and mines pretty loud.

Heard a 1996 gt with a Mac Tru Fit 2.5 inch catback with flowpath mufflers, and a bassani o/r x-pipe. Talked to the guy for a few minutes, and the car sounded sweet the whole time it was ideling, however, when he shifted, or let off the gas, it sounded like the thing was backfiring. I have heard that this is the expanding/contracting of the x-pipe. 2 days later, I heard a 1997 gt with the same catback, and a Mac Prochamber o/r H-pipe, and there was no backfiring. Also, it was much louder than the x-pipe. If you ask me though, nothing beats a off road h-pipe with 2 or 3 chamber flows. :D

well the backfire when he shifted was cause he had a leak in his exhaust, i know cause it happened to me and freaked me out. my 02 sensor block off (carb car) backed out and it was backfiring in the exhaust.
