Post MORE POWER for 97 OBS: Where do I start?

What's the cheapest/easiest/fastest way to increase horsepower in my '97 Outback Sport?

New Air Intake @ $175 for +13hp?
Underdrive Pulley @ $159 for +5hp?
New exhaust?

Thanks for your input.

Thumbs up

I'd go with an intake, since you'll improve your fuel efficieny as well when you're increasing performance... the I'd do the exhast... and lastly the underdrive pulleys...

The cheapest way is probably take out the resenator box inside the passenger side fender. By doing this, engine will draw cold air in from the fender instead of warm air inside the engine compartment.

You may upgrade the stock filter to a performance unit to boost the flow rate a bit.

Check the post on COBB Tuning dyno results -- you're not going to gain any hp (maybe a little tq) from intake, exhaust & pulley.

Either put those bux into better tires/suspension, or save them for a turbokit.
