I tried the Fabspeed pipes and they did open up the sound somewhat, but it was a modest change for my tastes (but the price is right for the Fabspeed pipes).

The AutoThority chip cost 1.2K and you can immediately tell the difference. They do a lot of remapping of the ECU at low and moderate rpm's, not just at peak HP. I suspect the HP increase is only 15-20 hp for the 2.7L, but the car is far more responsve, I have been very pleased.
