Has anyone personally installed a PSE exhaust on a 991S?

I am sure you are right about location and climate, but why they use such shoddy bolts is beyond me.

Sadly not. All 6 bolts connecting the muffler to the cats sheared, and 3 of the 4 bolts on the sleeves sheared also. I can't attach either muffler at the moment because the holes in the flanges on the cats are still full of the old bolts. Nightmare. The material is too hard to drill or tap out. They now need to be torched and pulled, which is beyond my garage mechanic ability.

I was able to cut the straps that the bolts tighten on though. You can see one of them has been cut in this photo and has sprung open. Once these are cut fortunately the sleeves don't seem to get stuck on the pipe and will slide right off. I did this with a metal cutting wheel on a Dremel if that helps pull it into something you could do. You could possibly Dremel off the nuts on the cat bolts too.

Have you tried drilling into the bolt (by first starting with a small easy to drill pilot hole, then using a large drill bit to "catch" and rotate the bolt free?

P1433 - "The fault code is not found in the database"
P1672 - "The fault code is not found in the database"
The device apparently doesn't know what those two fault codes are.
Looking it up on RL, apparently, P1433 is the fault code for the exhaust vacuum: https://rennlist.com/forums/991/9989...433-error.html
In case anyone in the future reads this, yes, the iCarsoft POR-II was able to clear out both of those. No more fault message on my dashboard.

I just realized I bought the wrong combo switch! I ended up buying the one for cars with glass sunroof instead of metal sunroof (I have a metal sunroof). i.e. I bought 991-613-957-07-DML instead of 991-613-959-07-DML.
Does anyone know if I can just take the sport exhaust button (it's just a little plastic piece) from the new combo switch and install it on my original combo switch -- then have the dealership reprogram that? Or is there something actually different about the 991-613-959-07-DML combo switch?
I'd hate to have to return this this thing to get the correct unit if all I bought this combo switch for is that little plastic PSE button.

The iCarsoft POR-II got delivered today. The two fault codes that were present were:
P1433 - "The fault code is not found in the database"
P1672 - "The fault code is not found in the database"
The device apparently doesn't know what those two fault codes are.

Guys can anyone confirm that part number 991-111-437-07 is indeed the PSE center exhaust? All the parts websites selling this part number shows images of the standard exhaust which look like the top picture.
The PSE Porsche sport exhaust part number should be 991-044-200-06 and looks like the bottom picture.

Just got a C2S and without any previous 911 knowledge I went and install the PSE following this thread. Thanks to all who contributed.
While it seems overwhelming it is pretty straight forward. You can minimize prices by reusing your exhaust clamps, nuts, reusing your vacuum hose you are pulling out of the non pse exhaust and reusing the two vacuum clips.
The hardest part for me was taking off the airbox and putting it back in. If I were to do it again, I would have taken the wing off to get direct access to everything. You can not reach the long vacuum line without taking the airbox off.
Total working time I would guess between three and a half and four hours. Again all by myself following directions from this thread. If you are a bit of mechanical incline, save yourself some money and do it yourself.
Now I need to take the car to the dealership to get the button programmed.

Hi all, I know this is reviving an old thread but does anyone have the Porsche instructions for installing PSE on a NON S (Base) car? Biggest thing for me is the vacuum lines (which the base does not have). Please advise, thanks you! -Dom

I have a full oem pse exhaust forsale in the classifieds along with the rear valence if anyone needs one.
