JCR Superlight Race Silencers for 991.2 Porsche 911 GT2 RS

JCR Superlight Race Silencers for 991.2 Porsche 911 GT2 RS

The JCR Superlight Race Silencers for the 991.2 Porsche 911 GT2 RS are high-performance, non-valved exhaust upgrades crafted from lightweight Inconel and titanium, designed to maximize power, torque, and sound while significantly reducing weight by up to 9.3kg (20.5lbs) for enhanced handling and balance. 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 require tuning to avoid check engine lights. Both options offer seamless OEM fitment, retain factory exhaust tips, incorporate advanced heat shielding, and deliver peak gains in the mid 30hp range, making them ideal for GT2 RS enthusiasts seeking superior performance and sound.

Light Weight

• JCR has reduced the weight of the factory GT2 RS exhaust system, originally 13.34kg (29.41lbs), by a substantial 7.44kg (16.40lbs) through the use of lightweight materials and innovative design. This significant weight reduction offers notable benefits in any performance vehicle, with amplified advantages on this platform, as it minimizes rear-biased weight distribution to enhance overall balance and handling.

Direct Replacement / OEM Tips

• 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 provided hardware. JCR’s Superlight Race Silencers maximize performance while retaining factory exhaust tips for a stock-like appearance, delivering both performance and aesthetics.

Versions

• Race Silencers: JCR incorporates HJS’s renowned high-quality 200cpi motorsport silencers, replacing the restrictive factory assembly to significantly increase exhaust flow without triggering check engine lights, ensuring both performance and reliability.
• Silencer Deletes: JCR’s Inconel Valved Silencer Deletes remove all restrictions to maximize performance and sound, though they may trigger a check engine light despite an integral mechanical solution with the secondary lambda boss. To protect the turbo from foreign objects, JCR includes Inconel ‘Gravel Catchers’ due to the direct path to the turbo exhaust wheel.

Heat Management

• JCR equips each GT2 RS Superlight Race Silencer option with top-tier thermal protection as standard, utilizing heat shielding trusted in elite motorsport to manage temperatures and significantly reduce radiant heat effects on surrounding components.

Power Increase

• JCR has optimized the performance of this exhaust system while adhering to factory ECU limitations, ensuring power and torque gains without requiring a tune. Every component in JCR’s Titanium Exhaust line is designed to enhance horsepower and torque, with peak gains reaching the mid 30hp range in the most free-flowing configuration, alongside substantial improvements in engine response and mid-range torque.
