As I’ve mentioned before, vendors are now starting to produce GPF/OPF delete over the axles pipes ‘for non road use’

Here is the Fabspeed offering…

Here is the CARGRAPHIC Exhaust Valve Control Unit: https://www.cargraphic.de/en/your-vehicle/for-pors...

I may get one fitted on the 6th as their premises are on the way to the 'Ring.

They also do three exhaust types (Touring, Clubsport, and Racing), three tailpipes (open, rolled-in, and silenced), and OPF-delete pipes - see link below.

Does anyone know much about this company? Can anyone recommend or avoid their exhausts, for example?

Thanks mate. I think that they do fabricate in Germany but they may also fabricate in the UK still as well ...

I think the problem with all the GPF/OPF delete options, is unless you fit these to a non-EU car it will throw a check engine code.

The Fabspeed offerings can be found here:

Anyone offering a GPF delete has questionable morals IMO.
I don’t think GPF delete is right either for a road car, in a jurisdiction that requires it, but no different or less moral, or more egregious than de-catting or straight piping has been for years.

JCR have been testing 718 GT4 on track with OPF delete + Silenced Valved Race Pipe... have to say - car sounds awesome from the video posted on Instagram.

Assuming its marketed as for track use only and strictly no public road use.?

That’s certainly how other companies market and present their ‘catless’ products.
The onus is then on the customer.

For sound currently JCR imo (I bought one), however Akrapovic announced a titanium one recently, so will be interested to see how that sounds as it’s going to be cheaper than the JCR. Not sure there are any videos of it yet though.

Fabspeed, Brookes Racing and Supersprint all produce exhausts too. More and more suppliers are cropping up.

That’s interesting - JZM quoted ‘around £3800’ on Instagram but clearly they don’t know exactly yet. That link you sent may suggest otherwise.

£3800 would be really good, but I can't see it being that cheap. Won't know until they arrive though I guess!

Do Akrapovic have a sound clip / video yet?

On another note, I have been back and forward with Fabspeed, and they will be sending me a video next week with just their new exhaust (i.e - not the GPF delete).

I’ll post it here as soon as I get it.

Anyone gone for supersprint?
Must say it does sound rather good from the vids I’ve seen of it.

Dyno run of the JCR system now posted on YouTube:

https://www.youtube.com/watch?v=SQPAxLr4MvY

UK car, all stock except for the rear silencer replacement so the cats and GPFs are present:

OEM - 356.18WHP/275.87WTQ (409.61HP/317.25TQ)
JCR - 369.48WHP/287.06WTQ (424.90HP/330.12TQ)
GAINS vs OEM- +13.30WHP & +11.19WTQ (15.29HP/12.87TQ)

15HP from a silencer swap which is impressive smile Hopefully similar silencers would give similar gains if the stock silencer is so restrictive.
