RE: power of an H pipe
10 cool points?? Just kidding, some claim anywhere from 10-25, but that is coming from the manufacturer. It also depends if you have other mods: headers, cat-back. I think realistically it is 7-10. The sound is worth it!!

Would you still gain that much HP and torque if you had flows on the end of it and would it sound good with flows on the end ?

RE: power of an H pipe
the general consensus is that an O/R H pipe would add maybe 15 HP to the crank,,,,if you're luck and depending on other mods.
They also seem to say that the slowmasters are anywhere from 2-4HP less than straight through mufflers.
It all depends on your other mods and your tune though.
