Power Difference?

What's the power difference (tq & hp) between DI/DO, SI/DO, and SI/SO exhausts?

Except on a drag strip none are much different from stock really. Unless somebody has a before & after dyno test they could post.

I imagine better airflow has to help some, especially when used with a good CAI.

and then it all comes down to brand of muffler being used, size of pipe in and size out, how long is the pipe, etc....

True. I was lookin' to see if there was a big difference between the 3. For instance, is there a big power difference between DI/DO and SI/SO, or is the difference mostly in sound and looks?
