I was talking to my local exhaust guy and he was advising me against BBK mid H-Pipes, he said they liked to hang down? anyway, why does AM only carry 2 BBK and one Pypes H-Pipe? And why the hell are x-pipes so much more?

[AMChrisYoung]

X-pipes are usually the more popular option for our exhaust customers, which is one reason we have more choices for X-pipes than we do for H-pipes. We do want to keep a good variety of H-pipes in stock, though, which is why we offer both BBK and Pypes. These are two of the most popular, best-known brands in aftermarket exhaust, and our customer feedback about them is overwhelmingly positive.

We're always willing to expand our inventory to include new or different parts, and we welcome customer suggestions. As big as our warehouse is, though, we can't carry every part by every manufacturer (though we wish we could), so the more demand you can demonstrate by way of a poll or a thread about a part, the better the chances we'll carry it are.

BBK's fitment sucks balls. I hate BBK Products and will never like them.

That being said, all midpipes will hang down alittle bit. All you do is, before you tighten it to your catback, put a jack under the crossover on the midpipe, jack it up alittle, then tighten the midpipe against the catback.

mell0 runs a Jegs off road H pipe (welded high flow cats on) and it sounds good with his Flows.

See this is why I like American Muscle, your customer support is probally the best Ive ever dealt with. When buying parts, or asking tech questions.

I try buying all my parts from American Muslce, but like any other site, they dont have every part for every brand available. But I always check AM first.

I thought the most popular h-pipe was the prochamber

[Shaun03GT]

Prochamber isnt an H pipe though, its a prochamber. Its a one of a kind. Like look, heres an H pipe:



Prochamber:



The box is chambered and muffles down the sound alittle. But gives a really good tone.

Theres differences in X pipes too, They have X pipes like Pypes and BBK, then TRUE X pipes like Magnaflow and Bassani (I think), the difference is a standard X pipe doesnt cross over, a True X pipe does.

Standard X pipe:



True X pipe



But a Prochamber isnt an H pipe, its a Midpipe with a box in the middle, that basically acts as another muffler but gives a great tone.

[86er]

both of those X's cross over, the pipes one has the sides cut out and rewelded, where as the bassani etc has the pipes entering into the open x

[v606er]

Exhaust makes no sense. The little cross-over in the H pipe seems so worthless. And who decided that it would be a good idea to join the 2 pipes in the first place? Why no just run straight pipes?

[Shaun03GT]

You cant run a straight pipe unless you run a gay Y pipe.

The H as a crossover is more for sound. The performance is from bigger pipe, no cats, better flow.

Also 86er, good point didnt notice that. But the Magnaflow will give a differnt tone then the pypes one. Performance wise? basically the same.

I think by connecting the 2 pipes together it ballances the back pressure, wich gives you better flow and performance.

I had a friend who's a engineer for midpipes. The cross over is just for sound.

Basically, yes. An H-pipe balances out the pressure so one pipe isn't louder than the other and you get a good exhaust note. On the other hand the X-pipe promotes scavenging, which is where you get the slight increase in power at higher rpm's over a H-pipe.

No, not basically. On a H-pipe (which is what I'm talking about since a X-pipe doesn't have a crossover pipe) it's just for sound. It would have the same performance w/out the pipe.

Evolution. Straight pipes were cool, but when you have straight pipes with a muffler on each one, every time a pulse hits the muffler it has to wait for the next pulse to help push it out. With a crossover pipe there is constant pressure on both mufflers. The firing order on our cars is 1234 down the passenger bank then 5678 down the drivers side I believe. The left pipe would have 4 cylinders exhaust and then the right side would have four. Without a y-pipe like stated earlier, that would sound funny.

wow, I totally agree with you there, I never expected a response like that, that's awesome. So would other members of the board with the BBK H-pipe be willing to chime in on the subject? Should I go BBK, or something else? I know I want an H-pipe though.

I am sorry, I misunderstood you because where I stand a x is a crossover and you didn't state h, so I was confused but yes still basically. You can't have 4 cylinders exiting from one pipe and then four from the other, it would hurt your performance as well as sound ricer, so yes I stick with basically, and your freind should have taken that into consideration before he made his statement. He's an engineer not a rocket scientist like me. At least thats what my mom told all her friends.

Why because your friend is an engineer? So what.

The middle piece, the crossover makes it so theres some back pressure there. It does do it for sound aswell, but its for back pressure. No back pressure means loss of power

someone throw some links @ me.... what do you think of this?

MAC 99-04 GT/2V 2.5 Off-Road H-Pipe (Bolts to Stock Manifolds) [MAC-43969] : Lethal Performance, Performance parts for Ford Mustangs

[drazga97]

Mac O/R H and Flow 40s sound great

[Shaun03GT]

Mac makes good products. Id go after that. H pipe will give you a muscle car tone, X pipe will give you an exotic type tone. X pipes make more power up top as well. Not much though, probally un-noticable amount
