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

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

The JCR Titanium Superlight Center Bypass Section for the 997 and 991 Porsche 911 GT3, GT3 RS, GT3 RS 4.0, GT3 Touring, and R is engineered to deliver significant weight savings, improved flow, and an unmistakable motorsport tone. The section is constructed entirely from ultra-lightweight titanium, it replaces the factory center muffler with a free-flowing 70mm design that reduces rear-end mass for sharper handling and increased responsiveness. The precision merge section optimizes exhaust scavenging for enhanced horsepower and torque, while producing a rich, aggressive sound inspired by Porsche’s factory race cars. Designed as a direct replacement, it retains compatibility with OEM or aftermarket tips using the factory-style connection.

Light Weight

• Through the use of thinner wall material and the same superlight exhaust tip flange featured on the JCR Race Exhaust System, JCR has created the lightest center bypass product available today. Weighing 6.08kg (13.4lbs) less than the OEM center muffler, this reduction in mass is not only beneficial overall but also delivers substantial improvements in handling balance by removing weight rearward of the 911’s rear axle.

The Design

• Extensive testing and development of the JCR Race Exhaust System allowed JCR to achieve measurable gains in horsepower and torque while producing a smooth, exotic exhaust tone. The JCR Titanium Superlight Centre Bypass incorporates new routing with a transition from the factory 63mm diameter pipe to 70mm over a smooth taper, merging into the same precision-designed collector used in the Race Exhaust System. Its 100% modular design ensures it is a direct replacement for the factory center silencer.

RSR Style Sound

• By integrating key design elements from the Titanium Race Exhaust System, JCR has replicated that same distinctive RSR-style tone in the Titanium Superlight Centre Bypass. As with the Race Exhaust System, the sound must truly be heard to be appreciated.
