I prefer the h pipe, but w/e. It's a matter of preference really. There's only 1 or 2 hp difference between an x or h. You wouldn't notice a difference anyways, except sound.

I believe it's like 15-20 hp...

I have an o/r h pipe and trust me, you'll notice not only a new killer sound, but a little gain in power as well.
The stock mid pipe is restrictive, but not 15 - 20 HP worth...
5 HP maybe...
And it's all about the combo and what else you have. Simply throwing an O/R H or X on the car won't gain you 15 - 20 HP. There is a good theory that says to work the exhaust back to front, replacing the cat-back first, then the mid pipe, then headers.
 
ha ha yeah right. i wonder what weight reductions you can do to the car because there is how you really increase your time i mean look at the *** cars all the have to make is like 4 hp because they weigh about 35 pounds

You're right. But at the same time, our cars are by no means heavy...compare to an f'body.
