The new 718 GT4 and Spyder has been receiving excellent reviews from magazines and customers alike, however there is one stand out point which is mentioned over and over. The sound! Gone is the soulful scream of the 981 GT4 & Spyder instead replaced with a flat and uninteresting exhaust note, drastically reducing the all-important fun factor of this otherwise fantastic car.

The introduction of WLTP regulations have seen the introduction of OPF (exhaust particulate filters) and very restrictive rear silencer assemblies into the latest generation of models. The OPF serves as an emissions device but has a secondary impact which is very obvious to anyone who's heard just how muted all of the latest generation cars sound.

We are releasing exhaust solutions for these OPF equipped cars, releasing performance and unlocking the glorious sound.

Direct Replacement / Modular Fitment

The JCR Titanium Valved Race Pipe is a full direct replacement product for the OEM 718 GT4 and Spyder rear silencer assembly. No fabrication required, simply remove the factory rear silencer and replace with the JCR Valved Race Pipe.

Our system includes titanium tips which are fixed on v-band clamps. Not only does this ensure perfect alignment every time it also allows quick changes at the track to our optional Titanium Silenced Tips which reduce sound levels by a further 6-7dB ensuring that all owners who plan to use their cars on track will have no concerns about excessive noise levels on strict track events.

Light Weight

Due to the construction and material choice we were able to achieve all of our performance goals plus reduce the weight of the OEM system by over 60% - This truly is a win-win modification saving over 10kg (22.04lbs) of mass from the rear of the car.

Performance Increase

Every component of the JCR Titanium Exhaust line is guaranteed to improve HP & TQ with to a varying degree dependant on the specific combination of parts.

Non Silenced

This version of our 718 GT4 / Spyder / GTS 4.0 Valved Race Pipe includes small diameter straight pipes in the valves closed exhaust route which results in a smaller delta in volume between valves open and closed plus a louder more aggressive sound than our Silenced version due to gasses passing through non silencers when valves are in the open position.

This version is recommended for those who wish to create a larger and more aggressive sound.

GT3 Style Sound

The sound signature of the JCR Titanium Valved Race Pipe has been engineered to match as closely as possible to our existing, very popular GT3 product line. Gone is the flat and dull exhaust note, replaced with a beautiful flat 6 tone accompanied by a more substantial volume upon request. Utilising the exact same merge design as per our existing Race Pipe products we have brought the 4.0L flat 6 installed into the 718 GT4 & Spyder into life with an exotic high quality tone, something that owners have been craving since the release of these models.

This system retains factory valve control, ensuring zero drone cruising with the ability to increase volume with valves open.
