+1 one this response!
Exhaust can really get you a lot of bang for the $$.
A good set of 1 5/8" headers but not just any header, the length of the primaries really matters in the 3.2L. You can't move the peak torque RPM much, it tends to be around 5800RPMs and the header length must match this RPM. Hint: do NOT use short headers! The optimal header primary length works out to be about 28"-32" for the 5800RPM point. Trouble is it's hard to find long headers like this.

I take my car to Mexico every year so a safety margin for gas is just good sense and an aftermarket chip is out. I upgraded my car with the last chip that Porsche made for the 3.2s: #1267355358. It is the same as the ClubSport chip without raising the redline.
I had a discussion with Jerry Woods and Bruce Anderson about what you can do with the 3.2 and their answer was very clear. "There is 20 HP in the exhaust. Porsche didn't leave any power on the table in the intake or anywhere else." In other words a good set of 1-5/8" headers/heat exchangers will make you some power. Plus you can have fun selecting a muffler that will make you smile.
If you want more from the engine you will have to make changes so it pumps more air through it. That means: Turbocharge, supercharge, spin it faster, and/or increase displacement.
All of those means you either open up the motor and make changes or replace the motor.
