JCR Inconel Non-Valved Side Silencer Bypass for 992.2 Porsche 911 Carrera GTS and 4 GTS / Targa 4 GTS

JCR Inconel Non-Valved Side Silencer Bypass for 992.2 Porsche 911 Carrera GTS and 4 GTS / Targa 4 GTS

The JCR Inconel Non-Valved Side Silencer Bypass is a direct replacement for the OEM side silencers on the 992.2 Porsche 911 Carrera GTS and 4 GTS / Targa 4 GTS. Designed for maximum performance and sound, this non-valved system deletes the factory valve function and comes with an electronic valve delete module to prevent any codes or errors. Crafted from 100% Inconel 625, the bypass provides a significant weight saving of 10.68kg over the OEM side silencers. It is guaranteed to improve horsepower and torque, along with better engine response and a boost in mid-range torque.

Light Weight

• Through the use of lightweight materials and clever design, JCR has managed to significantly reduce the overall weight of the factory 992.2 Carrera GTS exhaust components. While removing weight offers great benefits in any performance vehicle, the gains are amplified on this platform, as reducing the rear-biased weight distribution helps to improve overall balance and handling. With this product installed, JCR saves a total of 10.68kg (23.55lbs) from the weight of the vehicle, which represents a significant 80.42% reduction.

Direct Replacement

• All of the JCR 992.2 Carrera GTS exhaust components are a direct replacement for their OEM equivalents, with a guaranteed perfect fit every time. No further work is required during installation beyond removing the OEM part and replacing it with its JCR equivalent and any supplied hardware.

Non-Valved Design

• JCR’s Non-Valved designs delete the factory valve function so that the sound is completely derestricted across the full range of RPM. Their Non-Valved components include electronic valve delete modules to ensure zero codes or errors, which would ordinarily occur when removing the factory electronic valve actuators.

Power Increase

• Every component of the JCR Titanium Exhaust line is guaranteed to improve horsepower and torque, with varying results dependent on the combination of parts. JCR’s most extreme free-flowing system will see gains in the mid-40 hp range on this platform along with great improvements in engine response and a big boost in mid-range torque.
