Hi everyone. I have a non-PSE 991.1 S. I bought a used PSE muffler. I've read all of the install posts - I think I can do this "factory style" and do it right. But I do have one question... instead of running the vacuum tubing from the COV the way it is outlined in the Porsche retrofit bulletin, could I just extend the passenger side non-PSE muffler side tubing to the center point PSE muffler connection with one simple extension?
I guess what I am asking is - if I don't need my install to be "factory style" to feel good about the setup - but do need it to be functional - wouldn't it be easier to never have to get into the engine compartment and route the vacuum hose through the oval heat shield piece - wouldn't it be easier to simply cap one of the non-PSE vacuum lines and extend the other to where I need it to go on the PSE muffler?
Thanks for your help and advice.

Thank you. Agreed on the tubing - I think I'm going to use some silicon tubing from Summit Racing.
From what I understand, if I plug/clamp the native tubing from the non-PSE exhaust and don't connect any tubing to the PSE exhaust, it will be in "PSE on" mode at all times. Would there be any issues with this from the vacuum pressure perspective?

i'm either dumb or lazy (or both?), but i can't seem to find the official porsche retrofit bulletin online -- any chance someone has a link handy?...any particularly helpful forum posts would be appreciated as well (i've searched a bunch and found many references to threads, but can seem to find the threads themselves)...this is for a 991.1...thanks in advance!

Make sure they take your VIN and provide the correct part number accounting for all the other options in your car.
