A Layman's DIY on removing a Porsche Exhaust
I put together a DIY video when I recently swapped out my PSE exhaust. I believe the work is identical for the non-PSE exhaust.
If the car hadn't had significant nut/bolt rusting problems this video would have been pretty danged straightforward and I'd bet I could have done the removal in less than an hour, jacking up the car included. However, my car had lived its first 20k miles in Utah and had been exposed to significant winter driving conditions, so the nuts and bolts were the most rusted out I had encountered on a 911. So I started the video with an optimistic tone but ended up with having to do extra work to remove the sleeves that go between the center and side mufflers and the exhaust tips.
I don't show the failed attempts to remove the seized/rusted-out nuts/bolts for the sake of brevity. Fortunately, all of this was still conquered and the cut-out parts have stock replacements.
Originally this was going to be a DIY install for the Soul Performance Products exhaust but I decided to break it into two segments. This is the first. The work here is applicable to any aftermarket exhaust install in any case. I think it is also useful for those with clean exhaust hardware, you can just skip over the cutting parts and breeze right through the removal. And for those with hardware stuck like mine, it will give you one workable approach for solving it.
BTW, for those that have done work on a 997 exhaust, I found everything on the 991 to be much easier to access.
Disclaimer: I'm not the greatest mechanic, so others may have a better approach on how to deal with the issues I encountered. This is just how I did it. Please feel free to provide any recommendations on improved approaches!

Someone asked recently whether the PSE can be removed without removing the rear bumper cover and bumper. From watching your video, I gotta say it seems removing the rear bumper makes it a lot easier.

IMHO: The only thing that made it difficult in my case was cutting the straps. Without that it would have been pretty easy from underneath. All of the bolts are made to be accessible from below.
My general philosophy is that if I don't have clear gains from removing something, then I don't since that removal could break something other than what I was trying to do in the first place (and yes this has happened more than once). In this case, you would have to remove the taillights, the bumper cover, and once that is off, the rear heat shielding as well. All unnecessary work and risks to me. I'd bet it would take substantially longer that way too.

Great video, your patience and tenacity is to be admired. I am going to doing the center muffler delete and an install of a GMG racing exhaust on my GT3 in the next couple of weeks. Being a bit long of tooth, I am working up the courage to face the a few days of post install neck pain, along with other reminders that I am no longer a kid. I refuse to give in to malady's of getting older. This is a clear case of an old Joni Mitchell lyric. "the head says no but the heart says go"!

StormRune - Not a bad job. I hate working with cars from the North East. That being said, some of the best fabricators I know come from there .... necessity being a mother, and all that.
Frank - When the time comes, by all means shoot me quick emails if/when issues arise. I'd be happy to point you in the right direction.

Larry, I hadn't seen your DIY before. It came along before I had my 991. It's very nicely done!
For those wanting to see how to do the removal in a photo-based thread WITH the bumper-removal approach this one is good to follow.
