PORSCHE GT4 EXHAUST UPGRADE! JCR Titanium Valved Race Pipes Installed

It had to be done! My Porsche 718 Cayman GT4 can now sing more freely thanks to the installation of a JCR Titanium Valved Race Pipe exhaust system. Heading out to JZM Porsche for the work to be done, listen to the improvement with the before and after!

Visually, we've given the GT4 a new look with the Inozetek Midnight Purple wrap at Dub Customs, and fitted the Aurum Gold wing risers from RSNV to match the wheels, but this next modification is all about the sound. To carry out the work, we're out to JZM Porsche, a specialist with a showroom featuring some fantastic cars, to get the Shmeemobile up on the ramps.

In step JCR Developments though, with the perfect solution for the 718 Cayman GT4 in the form of their Titanium Silenced Valved Race Pipe. The system is significantly lighter than standard, and brings back a lot of the sound that is muted thanks to the 718 being fitted with OPFs. It's a direct replacement while still offering valves that are controlled by the system inside the car too. I've opted to finish the system with the black ceramic tips to match the look. This is the specific system: www.jcr-developments.com/pors... )

Needless to say, this instantly awakens the sound, from the initial start up to the first drive to get a taster of what it's like!

    The GT4 has a fantastic engine, although for the 718 from factory it's muted compared to the older 981 version. However, there's a perfect solution for that from JCR! What do you think of the new sound of the car?!

    Shmee150 Great Video I think your 718 Cayman GT4 sounds way better and I think that JCR Titanium Silenced Valved Race Pipe Exhaust tip Black Ceramic Tip looks absolutely incredible

    @Shmee150 are you going to do the most essential upgrade - gearing change?

    after the change a more deeper grumble with a just more natural and raw note to it. Good choice sounds like it should now : )

    Sorry the standard exhaust is pitiful as eu regulations! But that jcr exhaust sounds awful! Two pipes caped Off! Never seen that before. Expected a lot better sound than that, and I bet it cost thousands!

    sounds great! I have a Gt4, love it. have you heard the non silenced version? cant decide between the two.

  19. Harry Atkinson

    Harry AtkinsonPřed 27 dny

    Any plans for a valve controller? Static rev comparison between the new and the old is kind of pointless (although thanks for trying), even with the sport exhaust button pressed the valves close at about 2000 rpm and re open at about 4000rpm the static soft limiter is 5000 rpm. A valve controller from Cargraphic will allow you to have the valve open when you want or return to factory operation via the button.

    I love the colour, just not sure on your Porsche, it’s a bit too glitzy, which if you’re a glitzy guy is great, it’s a bit Ibiza, pride etc. Now that Orange metallic GT3 RS with the silver rims, yes that car f**ks........

    @Princess Peach yes the substrate is there for sure, same as any non monitored OPF; ie US market

  38. Princess Peach

    Princess PeachPřed 28 dny

    @JCR Developments I read that due to fuel quality in Aus if they were added ten they would break or not work so not fitted... according to Porsche themselves. So the housing is there and the panel too? And if it breaks whatever?

  39. JCR Developments

    JCR DevelopmentsPřed 29 dny

    They still have the same substrate, albeit non monitored. The sound is identical

    OPF is this model’s biggest problem. Arkrapovic link pipes are a better value for a better result in my opinion. That’s what I am putting on my GT4 next month. Albeit, Both GT4 options are still pretty bad comparing to the sound of my 997.2 GT3RS with Akrapovic headers on it.
