Wondering if anyone can confirm for me that these are the correct lines for me to try and disconnect and plug before I begin.

I did a search and couldn't find any PSE equipped threads, even on the "other" forum. I've found videos on the net of the current gen gt3 disconnect also. Pics below. Any help appreciated, thank

UPDATE- I located the valves and vacuum lines with help from storm. They are in a serious Pita to reach spot directly behind the bumper. Not made of rubber tubing like other non PSE or GT3cars. They are made of some wire mesh tubing that is difficult to budge.

Another strange thing is that the valves aren't connected independently like in other units I've seen. appears to be a master and a slave unit. See pics below. Thoughts everyone? Anyone out there successfully completed this?

Negative those are your cats and the 02 sensors associated. Your vacuum lines should be center stage on your center muffler for a pse equipped car.

In the attached image (shown top-down), the number "3" is sitting right next to the vacuum valves on the PSE exhaust. Look for the vacuum lines that connect to these.

Thanks guys, I'll put up pics and sound clips when I finish. It will most likely be by tomorrow before work.

You're trying to unplug the PSE vacuum line and cap? Look at the pics I posted in this thread: https://rennlist.com/forums/991/8190...on-a-991s.html.

It might be difficult to accomplish your task without removing the bumper cover and airbox.

What does unplugging this do? Just make it so you have to hit the button? Does it still not kick in until 3k rpm?

Unplugging the vacuum lines from the valve puts the PSE in loud mode all the time.

Were the steel braided lines the ones that you need to remove and cap? I’m trying to do the same thing but this looks more difficult than what some people explained.
