That lettering on the back is terrible. Guy must have been drunk when he put the 9 on.

The pipe welded to the turbo is appalling. This is how you straight-pipe a 991.2:

Truly a "straight pipe" and what was used? JB Weld?

Any complaints on how this sounds? Much resonance in the cabin? I run a sharkwerks muffler delete and am good with the bit of drone it produces but have been considering trying the full monty with cats and headers. I'll state upfront that I don't want to jb weld a track back to my turbos, so this looks...just a bit better

Cold start is straight up violent. For the ~45 seconds of high idle after cold start the car is far, far too loud. I leave my garage door closed until the idle drops lest I wake the neighbors three blocks over.
It sounds wonderful almost all of the time; not too loud, not much drone. From 2K-3K it resonates some*, almost as if it hits the perfect harmonic for the body of the car. On spirited drives I just keep it over 3K and it’s perfect. I don’t daily the car, and would not recommend my setup to anyone who does.
Quirks: it’s louder in Normal than Sport and Sport+. I drive it in Sport+ 100% of the time as I want the rev match and slightly quieter sound.
To-dos: deactivate/disable/plug the symposer to see if that reduces resonance.
* the resonance/drone seems to be lessening over time. I’ve heard that catalytic converters change over several heat cycles, and I do wonder if that’s what’s going on. I like it better several weeks in than I did at first. In fact, I was convinced I had to go back to stock the first few times I drive it. Weeks later, I’m pretty sure I’ll stick with it; I like the sound, and dripping 25lbs in the tail of a 911 only helps the driving dynamics.

One look at the emblems tells you everything you need to know. This owner should not be allowed to own a Porsche.
