most common are: High flow cat, high performance mufflers, CAI.

If you do all the top 3 you will probably notice quite an increase in power.


since you probably have an SE/SSE you probably have the lighter suspension, there are many upgrades there to stiffen up the steering and handling.

yes a tranny cooler will help but you should have a stock cooler because you have the SSE model

The peice on top of the motor that says 3800 on it. Also called "heat trap". Pull up on the drivers' side to remove.
