I am a rookie Mustang owner, but I have already began adding mods to my ride. I have a Magnaflow catback system with the glasspak mufflers, and am wanting to add a good mid-pipe to my system. First of all what is the difference between an h and an x pipe as far as more rumble and better performance ? Is there a diiference in brands ? Catted or off road ? Any help and advice would be great ! also if it helps any ,some of the mods I have added are as follows : BBK cai, BBK 70mm tb, BBK pulleys, Trikflow upper plenum, Hypertech programmer, ffrp 3.73 gears
another thread about mid pipes no way! lol.... welcome to the site man
to answer your question... in the order of how much power you will make.... an o/r x will make the most, and a catted h will make the least (over stock).
x pipes have kinda an exotic "nascar" tone to them while h pipes sound more muscle car-ish...
if you get an o/r pipe you will need MIL eliminators (they turn off your check engine light) because your computer will sense that you do not have cats and you will throw CEL codes (check engine light)
personally.... given the fact that you have a magnaflow magnapack system, i would recommend the o/r x... it will sound bad ass... people will know the sound of your stang.
you can do the swap yourself in your garage in about an hour as long as you have some tools and jacks stands. you will need an 18mm deep socket and swivel extension for the removal of the stock pipe.
get bassani or magnaflow mid pipes. bbk is alright for h but their x pipes for some reason kinda sound a little different because they are put together a little different. they are built a little cheaper in my opinion.
hmmm... tryin to think if i left anything out... oh... if you want to hear what a magnapack system sounds like with a x compared to an h... i will go find videos... i used to have both setups (the first among many lol) and the x was def the best of the two. give me a few minutes and i will find the videos
Cobraboy is mostly right. An X pipe will make more HORSEPOWER than an H pipe, but an H pipe makes more torque than an X. (In general, your car may be different, etc., etc.)
I agree with what he says about your magnapacks plus an xpipe. Probably that's the way to go. In general, chambered mufflers (like Flowmasters) sound best with H pipes, straight-thru (bullet style) mufflers are better with X pipes.
Biggest thing to consider -- go with whichever one you like the sound of best. The power differences are minimal.

the difference between those two are night and day
horsepower and torque are directly related to each other... if you mod your car and it makes more hp over something else... it will also make more torque...

Of course. (i didn't word the "mostly right" part very well.
There are gains in both, but generally, an H pipe makes more torque compared to an X, and an X makes more HP than an H.
But the differences are fairly slight.

I will have to agree on x with the magnapacks for your ride, now keep in mind magnapacks are loud as is and with the addition with a o/r x will be very loud. i know a guy locally has 430s + that exhaust combo, that thing is very (ear bleeding) loud.I had flowmaster with a x and magnaflows with a x, definately magnaflows topped the flowmasters forthe x, now i am running macs (see sig) and i love it the best. but since you already have your catback i would just go ahead with the x.

the only thing to consider is cobraboy has a cobra obviously cobras promote more topend vs gts gts will benefit more from having a h to give more to there lowerend power vs adding a x which willgain some topend but not as much as they would gain on bottom end with a h.
i have seen it many times. i.e xxkazp3rxx when he had his GT we raced we had exact same mods but he had 390 gears vs my 373s he had a h with flows and i had a x with flows and i beat him at the strip, granted i have been to track more than him but he did cut me out of hole faster.

Thanks for all the info. I think I will go with an o/r x pipe. A local performance shop quoted me $229 for a bassanni o/r x. Does that sound about right?

If I were you, I'd buy a Bassani BX High-Flow X pipe. It comes with 2 high-flow catalytic converters. The entire kit is 320$.
Here's why. Without catalytic converters, you will fail emissions. If you buy the Bassani High-Flow X pipe, you can swap out the catalytic converters for straight pipe or cutouts (thereby making it O/R status). Keep the catalytic converters in a box until emissions time. Or, keep them around in case you don't like making people jump into bushes when you drive by.
I have SLP Loudmouth 1s and a Bassani O/R X pipe. I'm serious, people jump in the bushes when I drive by. I have a reputation in my town now... "That kid with the loud %$*@ing Mustang that drives like a granny"
Although, when I open the cutouts, it's a real treat for my town (I do it on purpose because I hate them all with a burning passion, but that's besides the point).
IF you like loud, then O/R is for you. If you like somewhat-loud but legal, then put the high-flows on- they don't hurt performance at all, they just don't sound as awesome as straight pipes.
AND if you do go with an off-road midpipe kit, you don't necessarily have to buy MIL Eliminators. IF you are serious about making your car go fast, buy a tuner. I recommend Sniper Tuning. You can fool your computer into thinking everything is alright back there at the O2 sensors. If the emissions place checks your emissions through the OBDII port, the computer will lie and say everything is ok (but not with the sniff test)
That, and you'll probably run very lean if you put on O/R pipes, so you'll need to tune anyways. Mine was running horribly lean when I put my O/R pipes on. After a nice tuning, my car ran a HELL of a lot nicer and had a throatier tone.
Hey dawrr, thanks for heads up. I have a Hypertech programmer that I got from the guy I bought the car from. Should that work for tricking the computer ? I have not personally used it, I only had the guys at the performance shop adjust it when I had my gears changed. I know what you mean in loud, my cuz has an 02 stang with Flowmasters and an o/r bassanni x and it sets off car alarms and scares children. Seriuosly, children actually go running and crying cause the thing sounds like a monster. I just want my family to hear me coming home. From a mile away !

That's an awesome tuner. That will definitely work.
If there's an option to disable the rear 02 sensors OR specify midpipes and/or catalytic converters, then you're golden.
And yes, your family will be able to hear you from a mile away if you're flooring it. If you are coasting, you sound like a distant motorcycle. If you floor it, there's an interesting "warble" effect along with the Nascar-sound. It's interesting and EXTREMELY different. I'm the only Mustang owner around here with it, so the Flowmaster guys are jealous
Hey Dawrr, thanks again for all the great info. I am going out tomorrow and getting the x pipe. Hey what is your opinion on headers? From what I have heard the install can be costly. Is it worth the money, and what are the benifits ? If not headers then what other type of mod can I go for in trying to add better performance and more vroom vroom ?

No problem!
Headers typically add more power than a catback. The install isn't horrible, but you're looking at a lot of time under the car. It was hard enough getting my arm up to the studs to install the X pipe. Removing the headers can be done without pulling the engine out, but it is a royal pain in the butt. Getting a garage to do it is probably best.
If you want more rumble, get longtubes (but for longtubes you'll need a slightly different X pipe because Longtubes are, well, long). Longtubes cost from 500-1000$. Shorties cost from 200$-1000$
There's multiple types as well. Equal length and Equal-tuned. They both attempt to time pulses so they extract as much exhaust as possible. Regardless of which one you choose, you'll feel a noticeable difference.
There are plenty of things that will make your car faster AND sound better. Cams are the next biggest thing. I haven't put cams in my Mustang yet (stock ones only), but from what I've read/heard/discussed, they hold the potential for 45hp/45tq on average. That, and they make your car sound downright nasty.
The downside to cams is the cost. A set of Comp cams will run you about 600$ for a 2V engine and 1300$ for a 4v (if not more). Installing them is best left to the shop, but if you think you can do it have at it. It's an expensive upgrade, but the results are worth it.
Look up "cammed Mustang GT" on Youtube.
You'll LOVE it.
Once again thanx for the great info. Man this forum is awsome ! I have learned more in two nights than I have in the last five months. That's how long I have had my stang. I will look into the cams .
X-Pipe vs H-Pipe. Which is better?
