H-Pipes

I have got another question! I have heard you guys talk about H-Pipes, but, what are they ? See, I just bought my Mustang and am wondering what they are? And, what would be good light mod's I could make on my 98'?

An H-pipe is what connects your exhaust manifolds or Headers to your mufflers. This is where your catalytic converters are located. The stock H-pipe has 6 cats, 3 on each side. For less restriction and more power, an aftermarket H-pipe is recommended. You can get them with no cats(off-road), or 2 or 4 cats to stay emissions legal where you live. An aftermarket H-pipe is the best exhaust mod you can do for more HP at a reasonable price.

An H pipe is just what it sounds like, just like T-Bone said, it connects the headers/exhaust manifolds to the mufflers.

If you took it off the car, it would look like an H...two pipes running parallel with a pipe connecting the two.
You could also look into getting an X pipe, which is what it sounds like...replaces the stock H pipe and looks like an X...that's as simple as it gets.

As for performance, if you want something you can feel, get gears.
4.10's
or 3.73's if you do a lot of highway driving (that's what I have)

Its called a H-pipe, because there the pipes from the left header and the right header are connected by a straight balancer pipe just before the mufflers. The resulting shape is a H.

One alternative is an X-pipe. This is similiar to a H-pipe, but instead of using a balancer, the pipes blend together into one large pipe, then spilt apart, forming an X.

Most after-market H and X pipes are offered in off-road versions, and catalitic versions. The off-road version has no cats and are illegal, but you can get away with it if you really want to. The catalytic versions usually have just 2 cats, 1 on each side.

In general, any aftermarket H or X pipe will provide more hp and torque, but H-pipes typically give better low end torque then X-pipes, while X-pipes give better high end hp.

If you bend down and look under the car, you can get a good look at how this is all put together.

You're right about the gears. That's the first modification a modular engined car really needs if the owner would like a little more umph.

(Knew I shouldn't have gotten up to get that coke mid-way though typing my post.
