Great thread this, A font of useful information!

I looked into doing this myself so this is a great aid. I'm getting a custom exhaust, so i'm glad it can be done without the need for a key fob. Makes the cost of a custom exhaust less if only a butterfly valve and solenoid are needed!


Pat on the back to you lads!

Excellent post Rob and well documented fella.

I know how much this time this has taken to put together and take my hat off to you Rob, I like the electronics part - brings back memories and I do miss them. Have a stash of bits in the loft, makes me want to put something together now - Well done !!

Salut thumbsup

Hi all - just to build on this excellent post from Ducati Rob (and Systec) I have now followed his instructions and successfully installed the PSE button to control my new Top Gear valved exhaust on my 997.2

A few minor differences..

- The connector on the 997.2 has 20 pins however it is still pins 10 and 11 that connect to the PSE button as per Rob's original posting https://www.dropbox.com/s/smvmpgk8pkqxjmb/20170917_171715.jpg?dl=0

- I just used two resistors in the voltage divider (100 ohm and 50 ohm) which gives the same result as the 3 Rob used

- I installed into two small project boxes which fitted neatly in the space behind the PCM https://www.dropbox.com/s/uz3srsma46gf3v0/20171025_171508.jpg?dl=0
This meant just one wire to be routed to the engine bay (see my other post on how to do this)

Switched live was obtained by using a piggy back fuse from the main fuse box https://www.dropbox.com/s/htr6qjras74dacr/20171023_163911.jpg?dl=0

The Top Gear exhaust looks good quality but not so sure about the electronic components. I decided to buy a Pierburg valve - which is what Porsche would have fitted as the OEM part
https://www.dropbox.com/s/pb8vjxggskud6ya/20171104_132009.jpg?dl=0

Everything working fine and I'm really pleased with the end result. I would summarise by saying its how the car should really sound from the factory. Not in any way too loud or droning - but just enough of a bark to match the looks and performance of the 997. Definitely a mod I would recommend to everyone. I should also say that I have also fitted the H&S crossover pipe to replace the rear (centre) silencer. I did this first and I know that there are various posts saying the 997.2 PSE is not loud enough with the OE centre silencer still in place - so I'd recommend replacing it with a crossover pipe as well

Thanks again to Ducatirob for the original excellent post. I would have been lost without it


Excellent job Thumb with some good improvements over my original. Definitely recommend the better quality solenoid valve, the one included with my topgear exhaust didn't last too long!

I love posts like this and really think it should be a sticky as "can I use an aftermarket valved exhaust with my PSE button" or can I retro fit a PSE button with my valved aftermarket exhaust " are questions asked so many times on here Thumb mods please give this consideration for a sticky. Thumb

Couldn't agree more Phil. I've had this thread saved as a favourite on my browser since it first appeared just waiting for the right time. thumbsup

Just found this excellent thread but have the pics disappeared from the OP's post or is it just my PC?

This is the missing circuit diagram (DucatiRob's).

I strapped two (not three) resistors across the relevant terminals of the latching relay (R1 is double the value of R2 and forget R3) and installed the assembly in a small plastic enclosure and mounted it under the PCM. This makes the wiring to the switch panel easy. You then run the solenoid control cable through the middle console under the carpet under the rear seats into the engine bay to the vacuum solenoid. I ran the cable through a grommet under the ECU as I couldn't easily install it through the large cable gland on the RHS of the firewall.

@DucatiRob any chance you could add the photos back to this thread? I’ve purchased the parts but could use some help putting it all together. Thanks
