JCR Inconel Valved Race Exhaust System for 980 Porsche Carrera GT

JCR Inconel Valved Race Exhaust System for 980 Porsche Carrera GT

JCR presents the Valved Race Exhaust System in Inconel for the Porsche 980 Carrera GT — an engineering solution designed to elevate one of Porsche’s most iconic supercars. Recognizing the Carrera GT’s legendary status yet untapped potential, JCR developed this system using advanced design principles and lightweight, heat-resistant Inconel alloy. The result is a notable increase in performance along with a dramatic transformation in exhaust tone — delivering a more aggressive and exhilarating sound profile, particularly with the roof removed, that enhances the overall driving experience.

Direct Replacement / Modular Fitment

• The JCR Inconel Valved Race Exhaust System serves as a direct replacement for the OEM rear silencer assembly on the Porsche 980 Carrera GT. No fabrication or additional components are necessary — simply remove the factory unit and install the JCR system to benefit from substantial weight savings, increased performance, and a transformed exhaust note.

Exotic Sound

• The sound profile of the JCR Inconel Valved Race Exhaust System has been meticulously developed to suit the character of this iconic vehicle. While the Carrera GT already delivers an exceptional tone, JCR identified an opportunity to elevate the overall auditory experience. The design preserves the factory’s signature note while enhancing volume, reducing mass, and improving performance. The system retains factory valve functionality, allowing for refined cruising with valves closed and a significantly more aggressive tone with valves open.

Light Weight

• Thanks to the use of Inconel and a carefully optimized design, JCR achieved all performance objectives while reducing exhaust weight by more than 57% compared to the original system. This results in a net savings of over 19.98kg (44.05lbs) from the rear of the car — an impactful upgrade in both performance and efficiency.

Bespoke Storage System

• Recognizing the rarity, value, and weight of the OEM exhaust system, JCR developed a custom storage and transport solution. The bespoke storage box ensures safe handling and preservation of the factory unit when removed. Additionally, it serves as a striking presentation case for the JCR Inconel Valved Race Exhaust System upon delivery.

Performance Increase

• All JCR exhaust components are engineered to increase horsepower and torque, with gains varying based on system configuration. In this specific application, the JCR Inconel Valved Race Exhaust System delivers a peak increase of 13HP and 11.4Nm over the stock rear silencer, along with a consistent performance improvement across the entire rev range.
