Special thanks to Eric from Supreme Power for the Akrapovic slip on race system with tips for my GT3RS 991.2. He was great to deal with and took extra care of my special shipping needs to Canada which only took 2 days. The system looks awesome and I am actually quite impressed with the tips. I was hesitant about the pricey tips but after looking at the construction with the small baffle inside I am quite impressed. Next up is installation next week where I will get some before and after revs from my stock system.
I need a valved system for the local track (and my neighbourhood)as others have gotten flagged just running a sharkwerks bypass. I am entertaining the thought of the complete Evo valved system. I want to run these a lil bit and then make the choice.

Let us know if you want to go full Evo. We just put it on our RS and love it!

Just had the Akrapovic installed by Supreme Power yesterday on my GT3 and it sounds great! Very impressed with the shop, install, and customer service. Thanks Eric and Kim!

Thank you El Cholo Loco! Hope you are loving it!! Appreciate the kind words!!
I'll echo the above comments and say that Supreme is a class act all the way, from customer service to the quality of work, and I've been more than impressed with the people and the shop. They treated the car like it was their own, carefully getting in and out and not ham fisting anything.
If you're in SoCal...they should be on the top of your list!
Got the Akrapovic race bypass and tips installed on the 991.2 gt3rs.
Impressions after 100km : Louder than stock but not obnoxious ( maybe 1-2 db). More sound on the lower end with a bassier note. Upper range it is quite similar to the stock note. No highway drone noticed yet. Overall the system has given the car a sportier tone everywhere and has woken it up to the next level .The tips are a bit larger than stock at 95mm (had sharkwerks on my old gt3 which were at 100mm). The Akra tips do come out further which I was not expecting and extend the car (maybe an inch?) You can notice the tips and length increase via the backup cam .
Power increase and weight saving: Butt dyno notices nothing and weight feels the same. Perhaps full system there will be a more noticeable difference.
What now: I got a track day in next few days where I will put in some more time and think about what next. Maybe I go full Akrapovic evo valved system or add just valveless link pipes which are quite a bit cheaper. Regardless I will give it a bit of time until I start to itch again.
Overall : I am happy with it. It is not obnoxious. It is a high quality component and suits the cars character. It does increase the note moderately. It should pass most track decimal tests I think. It is a good starting point.
I have the akra center bypass piece as well. Couple things I like about it in case you haven't examined in detail. 1) it actually bolts to the stock center mounting bracket, not just held in place by the clamps so dont have to worry about adjustments post install. Same as SW here. 2) Tips bolt on the same way stock does so you can change them out or keep your stockers but don't see clamps from behind the car the way others exhaust tips show. Seeing the clamps that hold the tips in place bugs me a lot for some reason. Also same a SW for reference. 3) It has a crossover pipe that connects both sides just like the stock center if you've ever seen a cutaway. Zero drone and I think this is part of the reason. 4) Really really light compared to SS systems and in addition to more volume has a really pleasant smooth tone. 5) Quality, its a work of art when you hold it and examine up close. 6) The tips are the perfect size and look like something more OEM than the other bigger pipes. (Btw, mine line up perfectly like the oem tips did)
