After my PSE install, the dealer had to order the cut off switch. I decided not to have it installed. It's been about a year and the sound is just right (awesome); 24/7. No complaints from neighbors and grins from passersby.

Re Short Shifter, not problems hear either; Love it

 

My fathers car as PSE... I think it sounds really sweet!! More aggressive than his old 996!! Only complaint I've had is that with the exhaust my dad can hear as I accelerate out of the neighborhood :-)

 

Sharkwerks of Fremont, CA just installed the complete AWE setup on my S....headers, cats, mufflers. The sound is unreal and the craftsmanship is best-in-class. The power gains are some of the best out there. I suggest all 997 owners who are considering exhaust to check them out.

 

AWE sounds perfect.
