9m Equal Length Heat-Sheeted Catted Headers – Porsche 981 Cayman / Boxster
High-performance 9m equal length catted headers for Porsche 981, featuring integrated heat shielding and optimised exhaust flow. Designed to improve power delivery, throttle response and exhaust tone.
Product Description
The 9m Equal Length Heat-Sheeted Catted Headers are engineered to unlock the true performance potential of the Porsche 981 platform.
Designed with precise equal-length runners, these headers optimise exhaust gas flow and cylinder scavenging, resulting in improved mid-range torque, enhanced throttle response and increased top-end power. The equal-length configuration ensures balanced exhaust pulses, delivering both performance gains and a refined, motorsport-inspired exhaust note.
Unlike standard manifolds, these headers incorporate high-flow catalytic converters, maintaining emissions compliance while significantly reducing backpressure. The result is a more efficient exhaust system without compromising drivability.
To manage engine bay temperatures, the system features integrated heat shielding, reducing heat soak and protecting surrounding components — particularly important for track-driven vehicles or high-performance builds.
Manufactured from high-grade stainless steel, the 9m headers are built for durability under extreme thermal and mechanical stress, making them ideal for both fast road and track use.
