    If you have an expansion chambered pipe... yes, you should see a difference.

    Rule of thumb is: You have to be able to get the flow out of the motor, before you can put more flow into it. Now you might be able to see a little difference with a stock pipe, but only if the intake/reed assy is really restrictive.

    Run the KOSO intake with intake stuffers to get the most power.

    With only a 20mm on a 90 I wouldn't mess with trying to restrict the flow with the stuffers. You said you have some mods and a pipe and most folks are running a 24mm at that point so you need all you can get out of the 20mm.
