I have an 89 Honda Prelude S. I want to gain some more horsepower. What can
 

i do, please help.?

The usual parts,















Intake, Headers, Cat, Exhaust.















Please get all three exhaust parts if you're going to upgrade the exhaust otherwise you'll be loud and still won't gain power do to flow restrictions.































The best mod would be to turbo the motor if it's still in good condition, or install a nitrious system if you don' t care about the motor and want to be fast.
