The ultimate high-pitched Equal-Length Header and Valved X Rear Muffler Package for the Porsche 987.1 and 987.2 is now complete.
The Porsche 987 Boxster and Cayman are among the most beautifully balanced mid-engine sports cars Porsche has ever produced. With their naturally aspirated flat-six engines, sharp throttle response, and lightweight chassis, these cars already deliver a highly engaging driving experience. However, the factory exhaust system leaves a significant amount of sound character hidden, especially for owners seeking a sharper, cleaner, and more exotic high-frequency tone.
To unlock the true voice of the 987 platform, we developed a complete exhaust package consisting of ultra high-pitched equal-length headers and a specially designed valved X rear muffler. This system is not created simply to increase volume. It is engineered to refine the exhaust pulses, improve sound clarity, and transform the flat-six engine into a far more emotional and race-inspired machine.
The equal-length headers are designed to optimize exhaust pulse timing from each cylinder, reducing interference and creating a smoother, more harmonized exhaust note. As engine speed rises, the sound becomes sharper, cleaner, and more extended, producing the kind of high-pitched tone that conventional exhaust systems cannot achieve.
The valved X rear muffler further refines the sound by allowing the exhaust flow to cross and interact through its X-section layout. This creates a more focused, metallic, and exotic tone while maintaining strong response and drivability. With the valves closed, the system delivers a more refined and controlled sound suitable for daily driving, nighttime use, and situations where discretion is required. With the valves open, the car transforms completely—unleashing a crisp, aggressive, and ultra high-pitched sound that brings out the full character of the naturally aspirated Porsche flat-six.
This package is designed for Porsche owners who want more than a conventional loud exhaust. It is built for those who seek precision, musicality, high-frequency sound, and a dramatic change in driving emotion. From low RPM refinement to high-RPM intensity, this system delivers a perfect balance of control, performance feel, and unforgettable sound.
Please note that the 987.1 and 987.2 models are not interchangeable. Fitment differs depending on generation, model grade, engine specification, and model year. When placing an order, please make sure to clearly provide your vehicle’s exact grade and year of manufacture so that the correct version can be supplied.
For 987.1 and 987.2 owners who want to experience the full potential of Porsche’s naturally aspirated flat-six sound, this Equal-Length Header and Valved X Rear Muffler Package is the ultimate upgrade.
