I'm in the middle of installing the PSE on my 991.1 S cab. It's a been really fun and totally doable. My wife and kids think I"m crazy having my new car in pieces in the garage.
So, the exhaust is on and vacuum lines are run. I realized I still have one of the two braided 190mm vacuum lines left over. I used one to go from the holder to the exhaust. I used the long clear vacuum line to go from the back of the holder along the frame. Should I have used the second braided line on the back of the holder and connect it to the clear vacuum line? I'd rather not take the exhaust again at this point.
It sound like you may have missed step 2.5.2 in the instructions, where the braided line is joined with the "plastic" Tekalan line, providing heat shielding to the part of the line that goes to the holder. I guess the plastic part might eventually melt or maybe it will be okay.
It's not clear to me how the plastic line would have attached to the holder though since I assume the braided line has a larger inner diameter for it to be able to fit onto the plastic part of the line... leading me the think the plastic line shouldn't have been able to fit onto the nipple on the holder since the holder was designed to receive the braided line.
Part of it is how much will it bug you (as well as whether or not it will eventually melt)l. If you decide not to go back and fix it up now, then you can always deal with it if and when the exhaust switching stops working. Part of the answer might depend on how hot the climate is in your location... but I don't know for sure if that will matter.
I went ahead and corrected it. It wasn't too bad taking it off and doing it right. Otherwise it would have driven me nuts.
Got it done and back together last night. Took it for a quick spin. A small rattle from one of the tips I I need to deal with. I didn't really open it up, but I'd say it wasn't as loud as I expected
Getting it programmed on Wednesday. I'm hoping that will give me the snap, crackle and pop I'm looking for.
I think we may have the same issue.
When I picked up my car from the service shop (not porsche), the mechanic told me that there was an “extra” flexi steel pipe that they did not use.
My PSE package bought from suncoast came with 2pcs of 190mm flexi steel pipe.
The service shop told me they only need to install one piece.
Now after reading your post, im wondering if the service shop missed that part 2.5.2 or suncoast really sent an extra piece.
By the way regarding the tip rattle your experiencing... i had that too... i DIY fixed it in my garage.
I discovered that the rattle is coming from the butt of the tip having contact with the front tip of the exhaust pipe (mushroom headshape).
To fix this, you must leave a gap between that 2 parts (1cm) before tightening the bolt on the tip.
Let me know if you have solution to it but this fixed my rattle.
I think you'll be fine with just the plastic tubing. It's such a pain to go back and add it at this point. Maybe keep jt handy Incase something it does melt or fail.
Thanks for the rattle tip. I'll check it out and report back.
Well, PSE programmed, but somethings up with the flaps. They seem to be stuck closed.
Tech said it's not throwing any faults. He said a changeover valve could be bad or maybe I missed a vacuum line connection. Tech said either would throw a fault.
If they are closed (meaning quiet), then they are getting vacuum since their resting position without vacuum (or disconnected) is open (loud).
Shortly after the car is turned off the vacuum should fall off and they should open. If you watch as the car starts, you should see them rotate to the closed position (assuming the PSE switch is in the off position).

Another PSE install question.
