    250sx exhaust ?

    are there any cores or plugs in the exhaust i can remove to gain a bit more power? i don't want to spend the $ on a new exhaust but a bit more power never hurts anything.
    any other free performance mods to be had?
    if i pull the airbox lid off do i need to mess with the jetting to compensate for the improved airflow?
    thanks.
