The factory exhaust, although slightly restrictive, is designed to be efficient, so you can keep it on. Change the fuel filter, coolant, oil, basically do a tune up on the car. Replace the air filter, spark plugs and keep your tires properly inflated to help MPG.How to make my 93 ford probe GT run more effectively?
Get a decent exhaust (around $300+ for a cat back) and a good Intake ( around $150 for a decent one)
