If I were to switch my catted H pipe out with an o/r H pipe what kind of gains would I be looking at?

nothing major, couple hp, a little better sound

thats the first thing i did after putting in 3.73's, i got an O/R Mac H pipe

sound definetly improved for the better, as far as gain...i didnt notice much personally but it did seem to run a bit better
