Awesome. Could you also use a db meter with stock compared to yours along with the quieter silenced tips you’re going to sell? Cheers.
We're completing a track test as we did with the 991 OPF Race Pipe products and will build a full data sheet for all of the various set ups.
Is it static or Drive by dB levels which you're interested in?

will you also provide a solution for the 2-4k rpm valve opening issue? I’d like to have the valves controlled by the standard button, but allow them to open much earlier than 4k - when needed... but not all the time.
do you need to make any electronic changes when you delete OPF? I dont see any sensors around them in the scarce pics?
Our system creates a much much smoother and natural transition, the valves work in conjunction with the factory exhaust button but the step is much more intuitive and makes more sense when driving in a spirited manner.
No changes required to electronics when deleting the OPF with our solutions. There are pre and post OPF sensors on the EU cars

What if I want to maintain the black finish look?
Tips are raw titanium, we can ceramic coat any of our exhaust offerings in black, thats no problem if you wish to keep a more OEM look.
The factory tips need to be removed otherwise the system is still restricted by the final element of the exhaust due to their very small internal diameter.

Do you make titanium exhausts for the 981 GT4?
A couple of images of some of our exhaust systems after some use..
Yes, we are releasing our 981 GT4 system offerings very soon!

The rear silencer replacement is very simple and quick. Around 1.5hrs maximum, very simple process with everything included and required.

We do plan to release a larger and more effective floor solution for the 718 GT4 / Spyder which will be compatible with our exhaust

Yes everything is retained as per factory, as you can see in the video the car is running with our exhaust with all of the factory body work in place. Clearances are actually larger with our system than OEM.

But there are big openings underneath the car now where the saddle type muffler used to be; not good for the efficient air flow underneath the car/diffuser!

Oops, this is for the previous GT4! Forget about my comment...

Dear Santa since it’s the holiday season could I have both? Cheers
OEM system is really very much compromised. We ditched the OEM tips due to the tiny and highly restrictive inside diameter.

No wonder your system saves weight, the OEM muffler looks so out of place on a modern car, big bulky and of course heavy!
I am following your companies progress, to bad that when the GBP is converted to the $CDN I almost passed out, although I can see the quality and appreciate the material choice.
OPF deletes expected early Feb and March we will complete the complete set up with the Race Manifolds

its hard to judge from a video if the sound level offered by this kit is what I’m looking for. My frame of reference for a perfect 6 cylinder sound was my 981 Boxster S with 200 cell sports cats and the standard PSE box. No drone, and an amazing scream at full throttle. I’m sure you’ve heard cars with that setup, how does it compare?
If I buy the current system on offering, will it be compatible with the OPF delete kit / header kit that comes in Februari? Just in case its not enough on its own. Or should I then wait for the full system.

Videos are always a bit of a lottery when it comes to truly capturing the sound. We have an OEM 718 GT4 which we are about to do some filming with vs the JCR equipped car which certainly helps give a sense and baseline.
Everything we're producing for this model is 100% direct replacement for the respective OEM component so you can fit at a later date and all of the OEM and JCR components are compatible with one another.
