Kline 718 GT4/Spyder exhaust

I'm close to pulling the trigger on Kline, but just want to finish doing my DD with this sizable purchase. Has anyone got Kline (SS or Inconel) OAPS & Box - and felt that the change was not significant enough or not worth the $5-8k ? Just want to make sure I will not have buyers remorse. From everything I have read the Kline is the way to go so I should be very happy with it.
So I have an inconel on order from @SupremePower

I've gone through this entire thread over the last few days, and seems to be a pretty unanimous sentiment that the Kline is worth it. A few have wondered if they should have saved some money and went stainless but I haven't seen anyone regret the purchase. In fact there's a thread on here where people list their favorite mods and the Kline exhaust got brought up multiple times.

I've had the Cargraphic Exhaust Valve Controller installed since DAY #1...which I leave OPEN in the "LOUD mode" 100% of the time. It just doesn't get any better...

I did go Inconel…weight saving is huge. Like you could carry the full setup in one hand and I also see its retain value and better investment down the road.

Will be picking up CPO Spyder this weekend - exciting after searching for a while. Have been following this thread with interest due to the unanimous opinion of current GT4/Spyder owners that the stock exhaust could be better.
Anyone in GTA/London area in Ontario with the Kline system that I could listen to prior to committing to the purchase?
People who did buy the Kline system and are located in Ontario, Canada - who did you buy the exhaust from and who did you have put it on. I know a few bought from SupremePower and had great experiences, just don't know if most shops who do exhaust work would be willing to work with an exhaust not sourced from them.
Never modified any of my cars previously, but feel like I may with this car given the stock exhaust sound. The sound is one of the main reasons I wanted to buy this car/platform as my weekend occasional track car.

I've got the Kline inconel system, OAP's and Back Box, installed on my 718 Spyder. I started with the SOUL Ceramic Coated Resonated OAP's ONLY, which I LOVED...and moved on to Kline. I get a huge smile on my face every time I drive my car. ZERO drone...just a truly refined, beautiful system.
I've had the Cargraphic Exhaust Valve Controller installed since DAY #1...which I leave OPEN in the "LOUD mode" 100% of the time. It just doesn't get any better...

The SS Kline I ordered a few weeks ago from @SupremePower will be at my house later this week. Mine took a little longer to arrive because I had Kline install heat shielding on the OAPs. While I can’t speak to the differences between stock and the Kline, I am pretty sure it’s going to make the car sound more “special”. This along with the JCR valved exhaust were the only two exhausts I could find that had that higher pitched Porsche flat 6 sound and were captured somewhat decent in YouTube videos. All the others I heard including OEM with aftermarket OAPs just didn’t sound as good as the Kline to my ears. I had the same reservations as yourself so hopefully, the change over will be worth it. Will report back once I get it installed and get a few drives under my belt. And will post some pics when it gets here before installation so you all can see what it looks like right out of the box with heat shielding installed.
Thank you!

The sound is an absolute game changer for this platform. I’m extremely picky with exhausts (went through 12 iterations on my old M3, as an example) and this one is one of the very rare occasions where it lived up to the hype and did not disappoint in any aspect of drone or impact to cruising enjoyment.
@dk3what not sure how mechanically inclined you are, but it’s a very straight forward install. Any competent shop that deals with European sports cars should be able to knock this out with ease.
