991 GT3 RS (OPF) / SPEEDSTER - TITANIUM VALVED RACE PIPE

Product detailed description

Weight Reduction

Thanks to its undamped 100% valveless titanium construction, the JCR Titanium Race Pipe offers our the most extreme weight reduction of the entire range. Reducing the weight of the 911's rear axle can make a huge improvement in handling balance. This modification saves almost 10 kg of mass from the rear.

Design

Through extensive testing and development, JCR has perfected a number of key areas in exhaust system design to perfectly have tuned and accentuated the tone and pitch of the JCR Race Pipe's sound and performance. The system features fabricated bends running down from the huge I/D directly from the OPF, reducing the 70mm diameter pipe to achieve the target level of back pressure to keep torque low, while still allowing the engine to breathe all the way to the 9000rpm redline . The system then merges into the next key point, collecting the gases and creating a cleaning effect, targeting unwanted drone frequencies before heading back into the dual 70mm 3-bolt 991 GT-style flange, allowing customers to select any OEM-style tip. 3-bolt flange. The valvetrain allows for direct mounting of OEM valve motors and retains all factory valve functions via a cockpit mounted exhaust button.
