Buddy has a 2001 Porsche 996 w/3.4L and stock exhaust. He recently purchased a pair of factory OEM Porsche sport exhaust mufflers from a local guy who was converting his car to a track only car and took them off. We want to install these mufflers but need the additional parts.
Can anyone please provide part#'s for what I will need to install them.
Right now have the mufflers w/ brackets and the associated solenoid etc... I "believe" I will need wiring harness, vacuum hoses and cabin buttons.

Also, anyone have a "how-to" or a link with pictures of a retrofit installation?

Finally, if it turns out to be too much trouble to do the wiring and vacuum what happens if we install "just" the mufflers? Are they in the "ON" mode without electronics and vacuum or the "OFF" position? In other words can we just install mufflers and have them be LOUD all the time?

 

You only need the extra parts if you want to mute the mufflers. The default setting is open. I hardly press the mute button; perhaps 1% of the time.

I had retrofit mine about 5 years ago. It required installation of the electrical system plus the vaccum tubes. You tap into the fuse box area, add the wires to the console and then run the wires to the engine compartment. You then tap into the intake plenum with a new vaccum tube and then run the tube to each muffler. It took me over 12 hours to install the entire system myself. I broke the project down in three days; the mufflers, electrical, and then vaccum.

There is a factory PSE installation manual posted on www.renntech.org.
