INCONEL RACE MANIFOLDS

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 models with the 992 GT3 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

Direct Replacement / Modular Fitment

Our Inconel Race Manifolds are 100% direct replacement for the OEM manifolds and are compatible with the OEM rear silencer section and any of the JCR Race Pipe products.

HJS 200 CEL Cat

The JCR Inconel Race Manifolds suitable for the 992 GT3 based models not only optimise primary runner lengths but also remove 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.

Light Weight

Due to the 100% Inconel construction the JCR Inconel Race Manifolds reduces the weight of the exhaust system by 3.86kg.

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.

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 Inconel Race Manifolds see peak gains of 21HP & 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

Power Increase & Real World Performance Improvements

Every component of the JCR Exhaust line is guaranteed to improve HP & TQ with varying results dependant on the combination of parts. Our direct replacement Inconel Race Manifolds will see gains in the mid 20HP along with great improvements in engine response and mid range torque.
