JCR Titanium Center Bypass Section for 997 / 991 Porsche 911 GT3, GT3 RS, GT3 RS 4.0, GT3 Touring, and R

JCR Titanium Center Bypass Section for 997 / 991 Porsche 911 GT3, GT3 RS, GT3 RS 4.0, GT3 Touring, and R

The JCR Titanium Center Bypass Section for the 997 and 991 Porsche 911 GT3, GT3 RS, GT3 RS 4.0, GT3 Touring, and R is a lightweight, high-performance upgrade that replaces the factory center silencer to improve both sound and driving feel. Offered in both Silenced and Non-Silenced versions, it gives drivers the choice between a more refined tone or a raw, race-inspired exhaust note, all while reducing weight to enhance handling balance. Built from premium titanium, it’s engineered for optimal exhaust flow, delivering sharper throttle response and noticeable performance gains. The direct bolt-on design makes installation straightforward, and it works seamlessly with factory or aftermarket tips for a tailored finish.

Light Weight

• Thanks to its 100% titanium construction, JCR’s Centre Bypass delivers a significant weight reduction at the rear of the 911. Any drop in weight benefits performance, but removing mass behind the rear axle offers notable improvements in handling balance, making this a truly rewarding upgrade.

Race Car Sound

• The JCR Titanium exhaust range is precisely engineered to enhance the tone of the 3.8L and 4.0L flat-six engines, focusing on producing the most aggressive sound under full throttle while maintaining a balanced volume at partial throttle and cruising speeds. The natural resonance of titanium creates a distinctive, hard-edged tone reminiscent of the latest mid-engined 991 RSR race cars.

Power Increase

• Every JCR Titanium Exhaust component is designed to increase horsepower and torque, with gains varying depending on the chosen configuration. In its most extreme free-flowing form, the system delivers up to 35 horsepower, along with sharper throttle response and stronger mid-range torque.
