981 PSE DIY Install.

Recommended Posts

Greetings everyone,

     I could use some help with a 2014 981S DIY PSE install.

     After much research I decided that the PSE was the way to go because of it's obvious options. In my mind, the PSE button install and ECU Flash sounded too much like Brain Surgery, involving the ECU in too much decision making. Either open the valve and make it loud, or close it and make it quiet. Gert Carnewal's FOB kit sounded like a perfect, easy solution. Just bolt on new mufflers, plumbing, and actuator kit. No interior demolition or ECU flash.

     My problem is that after buying the PSE "kit" through Suncoast, (nice guys) it came with no directions. After spending numerous hours reading through the entire internet, I have been unable to find any instructions on the PSE install. The kit came a plethora of hoses, Y & X connectors, and actuator valve. The Porsche Service department has all the information on a PDF file, but is reluctant to share. I know it's out there, somewhere, I just can't find it!!! 

     All I need is instructions on plumbing of the control valve & to exhaust butterfly, also torque specs of exhaust flange. If anyone could share this secret information I would be forever grateful. My hope is to photo and post a step-by-step for anyone wishing to do the same.

Cheers, Kurt

Your best bet is to go back to the dealer you bought it from and ask them for the instructions.


The longer story... a few years ago Porsche sold TSB updates on CD ROM - we purchased those and provided them here for people to view. Our cost on those TSB subscriptions was $450 per year - reasonable by our opinion.

Then several years ago Porsche dropped the CDs and now only offer TSBs (as well as service manuals, and wiring diagrams) via a leased PIWIS (or PIWIS 2) diagnostic tester.

The information is only provided on screen and some is not printable (i.e. wiring diagrams). Oh and the cost for a one year lease of a PIWIS -- are you sitting down --- $18,000 per year. No I did not misplace a zero that is - eighteen-thousand dollars per year.


So... if you can get the selling dealer to give you a copy that is your best recourse.

Even better if you did a copy scan them and upload them here for the next guy. Thanks.

     Here is a photo of the 981 PSE "kit" except for the mufflers themselves. My box included no instructions or parts inventory. It looked like the box had been opened but I have no reason to believe that instructions had ever been included.


     Just FYI, I was able to install the exhaust in well under three hours, including running around town to borrow a "flange tool" to spread the tail pipe to make it much easier to put on. It was all done on 7" ramps and two jackstands used only to support mufflers. The mufflers came off and went on with no clearance issues whatsoever. I didn't even have to remove the wheels, due partially to the fact that the car has 20" Carrera wheels and I was able to reach through the wheel to gain access to the left upper exhaust bolt. If I had the option to use a lift or the ramps, I would use the ramps, unless I had a helper/ holder.

Can you help with the same think :)

I bought muffler's included tips.

But I don't know what to order more, I know that I need new console with buttons.

But nothing more, do you have maybe parts number's and any instruction or photos ? Dealer said that they don't know, because they sell full packages...

Thank you very much.

Not much has changed since my original post a little over a year ago. I bought the "kit" from Suncoast Porsche in Sarasota Florida. It came with no instructions or part numbers. The only photo i have is the one shown above. I doubt you will have much luck getting information out of Porsche, unless you have a good friend in the service department. Sorry I can't be of more help. 

FYI, I'm still running mine "unplugged". It sounds great, runs great, and I can't see tearing my wife's car apart to install a button that we will probably never push.

Good luck

I have the complete factory instructions in pdf format for this from PIWIS. PM me & I'll send them.  I retrofitted the entire system no worries from these instructions including factory wiring/switch/dealer coding.  The wiring (not the switch replacement) & getting to the boxster engine/installing the vacuum lines is the hardest part.  Exhaust bolt in is simple.  I wanted the whole factory deal.
