Check out Carnewal. Gets pretty good reviews and not a crazy price.
I installed a Soul Performance non-valved exhaust and I am so happy with i every time I drive my car.
There is some drone at highway speed, but it is very livable IMHO.
I love the burble and symphony in Sports Plus mode! If you are thinking of an aftermarket exhaust or PSE, please at least talk with JOHN GAYDOS.

Yep. Modding 981(S) exhaust is really easy if you know how to weld. I gutted mine and it sounds just right now. I don't really see the need for valve/"quiet" mode. It's never that loud in 981 unless you go with straight pipe.
There is a multipage thread on this here somewhere.

I just installed a Carnewal GT exhaust on my 15 Cayman and am very happy with the results. I too felt the stock exhaust note was a bit too quiet. Its much better now. There's a noticeably deeper tone and it really wakes up in the upper revs 
Working with Carnewal was easy and it arrived from Belgium in 4 days. Hard to beat it. Good Luck.

Yes [mention]Will J [/mention] Cantrell is the US affiliate. Though Gert Carnewal does ship to the US from the EU and includes shipping labels. I’m close to convincing myself to order this exhaust based on feedback from others on the resulting sound.

Maybe you could show the forum what you did?
I am not the best at this but hope it works. In this thread post 12 and 13 I show what was done.
Porsche 981 S OEM Exhaust (w/o tips)
Removed from a 2015 Porsche 981 Boxster S with 30,000m. Unfortunately, I do not have the tips. Too bulky to ship but if someone lives close, I'm willing to meet you mid-way. I'm in the South Jersey area. This is the standard OEM exhaust, not the PSE version.

Actually I'm not happy with the noise level of my DIY "carneval" mod on my 981s.
It's really not as loud as exhaust on my M2, which is a turbo and by definition should be not as loud as NA...
I think I will be looking at fabspeed options this spring. I wish I could listen to straight pipe in person.

YT and in-person are different. When I was ready to attempt the Mod Cut#2 (my guess to be Carnewal GT), our fellow P9 member who did this mod on his 981S sent me a start-up and acceleration video clip. He left the muffler intact, cut the shell from below, cut 1.5" of internal pipe, and drove to muffler shop to weld the shell. I did not like the weld scar that is why I planned to cut the pipe internally using a die grinder. It sounded good until we met in a Home Depot parking lot to do a side by side with my stock non-PSE. He also gave me a ride to experience how it sounded inside. Wow, it sounded nice in person about 15% louder than mine, some pops & burbles and definitely more aggressive! He told me that it's not as loud and aggressive as a PSE from his comparison with another local car but better than stock for less than $75. He calls it as "matured sound".
It's the sound description I have read from Carnewal GT users (987/981).
To end my story 🙂, I was lucky to be gifted a free PSE from local P9 member (Canux) before starting mod#2 project (again, thank you very much!). As good as it sounds, my PSE has a nice story to tell to friends & relatives & car meet-ups.

Yeah can’t beat in person. I need to find someone with the carnewal and compare it to mine. If I did not have to fix a pool right now I would just get the carnewal and compare myself and sell one. I love experimenting and sometimes I cannot help myself.
