Porsche 992 GT3 RS | 992 S/T Superlight Race Pipe (Silenced / Race Cats) - JCR Development

Introduction

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 cars with the 992 GT3 / RS models being no exception.

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.

Our exhaust solutions for these OPF equipped cars release performance and unlock the glorious sound

Light Weight

Through the use of light weight materials and clever design we have managed to significantly reduce the overall weight of the factory 992 GT3 / RS exhaust components.

Removing weight full stop carries great benefits in any performance vehicle however the gains are exaggerated on this platform, reducing the rear biased weight distribution helps to improve overall balance and handling.

Our most extreme exhaust solution for this platform drops over 21kg of weight from behind the rear axle which yields real performance benefits in its own right.

Direct Replacement

All of the JCR 992 GT3 / RS Superlight Race Pipes are 100% direct replacement for the OEM exhaust system.

No requirement for any further work during install beyond removing the OEM part and replacing with its JCR equivalent along with any supplied hardware.

High Flow Silencers

Our Silenced version of the centre section provides a good amount of sound suppression versus our non silenced version, delivering a 5dB drop in volume versus fully non silenced on full throttle drive by noise tests.

All of the JCR Superlight Race Pipes feature a tuned merge for improved exhaust scavenging effect and a smoother and more pleasant tone.

Valve Delete

Our Titanium Non Silenced & Silenced options delete the factory valve switching function for a more pure driving experience and maximum flow.

All 992 GT3 / RS models feature electronic valve control which if removed without consideration will cause poor running and check engine lights. With this in mind, all of our non valved Superlight Race Pipes include our Valve Delete Kit which ensures no concerns for owners.

Simply install the JCR Valve Delete Kit and the car will run perfectly as per OEM.

Inconel 625 HJS 200 CEL Race Cats

The JCR Inconel Race Cat removes the factory OPF matrix and restrictive factory cat and replaces them with a high flow HJS 200 Cel cat. Flow is therefore greatly increased and improved performance comes as a result. For cars with no OPF monitoring our Race Cats in most cases will not cause any CEL and do not require any tuning.

In certain instances it's still possible for a CEL to occur. This tends to be if the car has poor fuel quality in the tank or excess load is applied when the engine and exhaust system is not up to full operating temperature. With this in mind, we do not guarantee that there is no chance of a CEL with these parts installed.

RSR Sound

At the top end of the rpm range, our Superlight Race Pipe configurations delivers that well know ‘RSR’ sound that we all know and love.

Testing Procedure

As with all JCR products we test our products extensively prior to release. We have been working on this particular product since 2021 and have shared an in-depth insight into our testing programme in a blog which you can find HERE

Power Increase & Real World Performance Improvements

Every component of the JCR Exhaust line is guaranteed to improve HP & TQ, dependant on the combination of parts. Our Superlight Race Pipes will see gains up to 26HP & 36TQ along with great improvements in engine response and mid range punch.

Optimising the manifold design along with deleting the highly restrictive factory catalysts and OPF’s (where applicable) not only brings a hard edged race car sound but also drastically improves flow resulting in increased HP & TQ whilst reducing temperatures significantly when driving hard on the road or track.

We found the latest generation Normally Aspirated OPF equipped vehicles have a strong tendency to actually reduce power output significantly on longer runs due to excessive heat build up.

Along with outright improved performance comes much improved consistency and even larger performance gains on longer track sessions versus OEM exhaust system. This is a point that we highlight again in our product release blog HERE
