JCR Inconel Valved Silencers for 991.2 Porsche 911 GT2 RS

JCR Inconel Valved Silencers for 991.2 Porsche 911 GT2 RS

The JCR Inconel Valved Silencers for the 991.2 Porsche 911 GT2 RS are high-performance exhaust upgrades crafted from lightweight Inconel to enhance power, torque, and sound while reducing weight for improved handling and balance. Designed as direct OEM replacements, they ensure seamless installation and utilize high-quality motorsport materials to optimize exhaust flow and engine response for the forced-induction flat-six engine. Available in two configurations, the Race Silencers feature 200cpi HJS motorsport cores for increased flow without triggering check engine lights, delivering a refined yet aggressive exhaust note, while the Silencer Deletes remove restrictions entirely for maximum performance and a bold, race-inspired sound, though they may risk triggering a check engine light. Both options offer significant horsepower and torque gains, up to the mid 20hp range, making them ideal for GT2 RS enthusiasts seeking enhanced performance and sound.

Light Weight

• By employing lightweight materials and innovative design, JCR has significantly reduced the weight of the factory GT2 RS exhaust components. Reducing overall weight provides substantial benefits in any performance vehicle, but these advantages are amplified on this platform, as decreasing rear-biased weight distribution enhances balance and handling.

Direct Replacement

• JCR ensures that all 991 GT2 RS exhaust components are direct replacements for their OEM counterparts, guaranteeing a perfect fit every time. Installation requires no additional modifications beyond removing the OEM part and installing the JCR equivalent with any provided hardware.

HJS Race Silencers

• JCR utilizes HJS, renowned for their exceptional reputation in producing top-quality motorsport catalysts. Replacing the restrictive factory assembly with a 200cpi motorsport silencer allows for significantly improved flow without the risk of triggering check engine lights.

Silencer Deletes

• With JCR’s Inconel Valved Silencer Deletes, all restrictions are eliminated to maximize performance and sound. Although JCR incorporates a mechanical solution with the secondary lambda boss, there remains a possibility that this product may trigger a check engine light.

Power Increase

• Every component in JCR’s Titanium Exhaust line is designed to enhance horsepower and torque, with gains varying based on the combination of parts. JCR’s most free-flowing system achieves peak gains in the mid 20hp range on this platform, alongside notable improvements in engine response and mid-range torque.
