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

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

The JCR Inconel 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. Crafted from 100% Inconel 625, this assembly is designed to provide significant weight savings and improve sound, power, and torque while retaining the factory valve control. The design features a new profile to optimize gas flow from the turbo flange down to the main flow path, ensuring maximum performance. It also improves throttle and transient boost response.

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 8.78kg (19.36lbs) from the weight of the vehicle, which represents a significant 66.11% 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.

Valve Function

• JCR’s 992.2 Carrera GTS Titanium Silencer Bypass section retains the factory valve switching function with no requirement for any additional controllers.

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 40hp range on this platform along with great improvements in engine response and a big boost in mid-range torque.
