start by getting the maintence done on it first like, plugs/wires (delco's), fuel filter, clean the throttle body out, service the brakes so the calipers are not draging (fresh lube on the slider pins).
then once that is done move on to getting more air in and out of the engine.
how much are you looking to spend and are you doing the work your self?
Probably not much faster, but it should sound nice. If it hasn't had a tuneup anytime recently, it will probably run better also. Do plugs, wires, O2 sensor, and fresh fluids at least.
yeah, i got a magna flow muffler and dual exhuasts at the muffler shop already paid for, i jus need to take time to go get them put on,
tune up and cold air intake
will these make it noticably faster or powerfull
