i'd recommend installing a catalytic converter. first, so your car doesn't smell like old wet turd. second, because it's a FEDERAL offence to not have one on public streets. if some drunk slams in to you and rolls your car, the officer might notice the missing smog devices. just because you may live somewhere emissions tests are not conducted, it's still federal law to have one. a $10,000 fine and jail time may result. third, a high flow catalyst will only effect performance about 1/2 horsepower, but will create that much needed 1 psi back pressure.
this is just a friendly warning. do what you want with your car. it's yours.
i'd recommend: porting intake manifold and installing 1zz throttle body; rear sway bar; lightweight wheels; lightweight clutch/flywheel; suspention
