Introduction

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 Inconel Race Cat OPF Delete Pipes are a full direct replacement product for the OEM 718 GT4 and Spyder OPF Pipes. No fabrication required and no additional parts. Simply remove the factory OPF pipes and replace with the JCR Inconel Race Cat OPF Delete Pipes.
Our Inconel Race Cat OPF Delete Pipes are also supplied with all necessary hardware to ensure an easy, hassle free install.
Heat Management

Each of the JCR OPF Delete Pipe options feature the highest quality thermal protection as standard. The heat shielding we have selected is used in the very highest levels of Motorsport to control temperatures whilst protecting and dramatically reducing the effects of radiant heat into the surrounding areas.
We performed 1000’s of miles of testing on track with each of our options with and without thermal protection and saw a consistent reduction of the inner rear tyre temperatures of 15-20c when running on track. This reduction in temperate yields a real world performance advantage over an OPF delete without a thermal barrier applied.
Race Cats

Our Inconel Race Cat OPF Deletes offer all of the benefits of our regular Non Silenced Titanium OPF Delete Pipes but with an overall reduction in dB levels plus the benefits of a 200cel HJS Race Cat. This means you benefit from the HP and TQ increase but with only a subtle bump in overall volume vs the factory OPF pipes whilst keeping the car emissions legal. This makes for a great option for those who run their cars on track with strict noise limits and for street cars which require functioning cats to be placed in the exhaust system.
Light Weight

Due to the 100% Titanium construction the JCR Titanium OPF Delete Pipes removes an impressive amount of weight from the factory exhaust set up. This truly is a win win modification.
Power Increase
Every component of the JCR Exhaust line is guaranteed to improve HP & TQ with varying results dependant on the combination of parts. Our most extreme free flowing system installed on the 718 GT4 / Spyder / GTS 4.0 will see gains up to +52.40WHP & +47.00WTQ (60.26HP/54.05TQ) along with great improvements in engine response and mid-range torque. Deleting the highly restrictive factory cats not only brings a hard edged race car sound but also drastically improves flow resulting in increased HP & TQ
