Introduction

The current crop of 4.0 Twin-turbocharged Porsche Cayenne’s are formidable in stock form however there is always room for improvements to be made, especially in the exhaust system.

Our direct replacement exhaust components not only save weight and improve sound they also deliver solid performance gains without compromise in a direct replacement part with perfect fit.

Light Weight / Inconel 625 Construction

Through the use of light weight materials and clever design we have managed to reduce the overall weight of the factory Cayenne Down Pipes by a significant amount. See below for exact weight savings.

Our Cayenne Downpipes are manufactured using Inconel 625 material which not only performs extremely well in high heat applications but also has an extremely high tensile strength which allows us to use thin wall thickness, thus reducing weight versus a stainless steel equivalent by up to 40%.

Direct Replacement

All of the JCR 9YA Cayenne 4.0 TT exhaust components are direct replacement for their OEM counterparts with guaranteed fit every time. No requirement for any further work during install beyond removing the OEM part and replacing with its JCR equivalent and any supplied hardware.

HJS 200 CEL Cat

The JCR Inconel Race Cat removed the factory dummy 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.

Heat Management

This product features 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.

Power Increase

Every component of the JCR Titanium Exhaust line is guaranteed to improve HP & TQ with varying results dependant on the combination of parts. Our most extreme free flowing system will see gains in the mid 30HP&TQ range with the stock ECU tune. Also expect great improvements in overall engine response, transient throttle response and boost building earlier in the RPM range.
