  • 991.2 GT3 RS (OPF)
  • 991.2 Speedster


From the 991.1 GT3 to the latest 991.2 GT3 RS, the factory exhaust system is somewhat a compromised piece. Porsche have engineered an exhaust system which will meet the requirements of each and every customer, from the every day driver to the most avid track day fan.

The introduction of WLTP regulations have seen the introduction of OPF (exhaust particulate filters) 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.

Light Weight

Due to the non silenced non valved 100% Titanium construction the JCR Titanium Race Pipe offers our most extreme weight reduction of the entire range - Any weight reduction is good news however reducing weight rearward of the 911's rear axle can yield huge improvements in handling balance too. This truly is a win win modification saving almost 14kg of mass from the rear.

The Design

Through extensive testing and development we have perfected a number of key areas in the exhaust systems design to perfectly tune and accentuate the tone and pitch of the JCR Race Pipe's sound and performance. The system features fabricated bends transitioning down from the huge I/D directly off the OPF reducing down to 70mm pipe work achieving target back pressure level to maintain low down torque yet allow the engine to breath right up to the 9000rpm redline.

The system then merges into another key point, collecting the gasses and creating a scavenging effect whilst targeting unwanted drone frequencies then heading back out into a twin 70mm to the factory 991 GT style 3-bolt flange allowing customers to select any tip using the OEM style 3-bolt flange.

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.

RSR Sound

For anyone who has heard the 2018 GTE 911 RSR in person they would be hard pushed to say that there is a better sounding race car. We worked hard to achieve that same glorious tone with the JCR Titanium Race Pipe on our non OPF system and have carried that same learning across to the latest OPF Titanium Race Pipe, hearing truly is believing in this case.
