i was thinking about drilling holes into my stock h pipe in order to possibly make it louder. You think it would change the sound in a good way? if not I am getting a new off-road x-pipe installed soon. has anyone ever tried this?

ok, i saw someone do it online at another site, and i guess he made a mistake. Another question, What exactly are cutouts? and are they cheap?
try one of the sponers.

Yes they are cheep, they are basically a Y, one end goes to the rest of the exhaust the other stright to the outside. It by passes the rest of the exhaust after it.

Provided you use it to bypass a restriction in the exhaust you'll see a HP gain. If you don't have a restriction after the cutout you'll see zilch'o gain in HP just one heck of a lot of noise.

A well chosen cat back and mid with suitable CATS will flow enough not to restrict the engine, in this instance a cutout would do nothing in HP terms.
