you def dont want to run open header on your honda, you will loose torque and possibly bend your rods. i've been told that if you run open headers that if you rev the engine and let off that air cold air can be sucked up through the header and bend your rods. i was told that by a honda mech who races, he put a three ft straight pipe after the header.
I really hope that isn't true b/c it is the dumbest thing i have ever heard...
taking off your cat will add power, and why do you want you car to be
louder ? most people try to make it crisp and quiet.
