X-Pipe vs. H-Pipe

coachfarnen · Oct 31, 2011

Sorry guys but I thought I would get the most responses in this forum about the exhaust for my 99' Saleen S-351.... I have an off road H-Pipe on there now but I've had this nice stainless Bassani X-Pipe sitting around doing nothing. I really like the sound of the H but I'm curious about the sound of the X. To me if I pick up 10 horse running the Bassani it's not a big deal. I'd rather sacrifice power for sound. Plus the X has a nice stainless look. So, the question is... How much tone at lower and higher Rpms could I possibly lose using the X vs the H??? Thanks

It's impossible to say unless we know what catback you are running.

The power difference between an X and H pipe on a sub-400 rwhp car is not measurable. You will lose/gain nothing switching between the two.

Its all based off preference, just for the hell of it install the X and see if you like it. Then you can mak your decision. Personally I loved the sound of an X piped Mustang but when I had my UPR X pipe on my car I hated driving with it bc my car is a DD. Now I have the Prochamber H pipe and I love it because its loud when I go WOT.

I noticed less rasp with the H-pipe and prefer that over the X I had. Not too noticeable in the videos but here's a couple. The rasp was mainly while shifting or on deceleration. Annoyed me.

Magnaflow catback, Magnaflow O/R X, stock manifolds
2004 Mustang GT Magnaflow Exhaust - YouTube

Magnaflow catback, BBK O/R H, BBK Longtubes
2004 Mustang GT Dyno Tuning - YouTube

Overall I liked the sound of both though. I've been wanting to hear a ProChamber with Magnaflows and longtubes.

I have a Bassani X-pipe and love it, I'd suggest putting it on and atleast giving it a try.

The exhaust from Header to tip is as follows... Ceramic coated factory Saleen unequal length headers, Standard off-road H (no cats), Stainess (I believe 3") pipes up to Flowmasters out to straight pipes....

Standard H vs Mac Prochamber.....

From what I'm reading here it sounds like the pipe of choice nowadays is the Prochamber as far as sound is concerned. I don't mind the drone and thoroghly love the cruising sound between say 1800-3000 rpm that the standard H provides right now. Will I notice a measurable difference between a standard H and the Prochamber???? Thanks

I have had an H pipe, prochamber, and X pipe. X pipe is my favorite. I can put up with the raspy sound down low for the absolute pure sex sound in the higher RPM's.

Stumbaugh · Oct 31, 2011

I shift my car at about 2,200rpm anyways, so I never hear the raspy part of the exhaust.

Def. going to try and bolt this baby up this week and give the X a shot....
What I'm wodering now is if there's a difference between the old school regular H and the Mac Prochamber?

I don't see how. The X is raspy at any RPM IMO.

It all comes down to what the individual likes in terms of sound. I had an X for 2 years and 2 cat back setups and hated both. The X sounds good at higher RPM but like ass down low. Once i swiched to an H I found that it's a more lower toned mellow note.

With that said. I personally think that when coupled to the right cat back an X can sound bad ass and the same goes for an H to some degree but you have less of a chance of screwing that up.

When DD my 87' GT with BBK shorties, Flowmaster cat back, and a MAC o/r H I personally think that it sounds 1000 times better than my 2V ever has even with the PI engine.

UPR X and Mac Flowpath's here... sounds sinister.

Stumbaugh · Oct 31, 2011

Yeah I remember hearing your car at Mustang Week burningrubber. Sounds good.

To me, the only time they are raspy, is when they hit about 2500-2800 rpm. Even that doesn't bother me.

That 351 is going to sound nothing like a 2v motor. I'd ask the fox body guys. On most motors, I always like the H-pipe, espeically the pushrod Fords. Good luck.

Twista · Nov 1, 2011

my 5.0 pushrod with o/r X and spintech mufflers
Cant really tell its an o/r X during the revving, but yes there is rasp

But i suggest you get the o/r H

I've had both and I happen to really like the bassy tone of the h-pipe over the scream of the x-pipe. Even in the upper RPM's the h-pipe gives off a really nice bassy note coupled with the high pitched mechanical symphony of the OHC V-8. In low-mid RPM's is where the h-pipe really shines. It sounds so damn good and aggressive
