Catless Exhaust Manifold for Porsche Boxster Cayman 981

Unlock sharper throttle response and increased naturally‑aspirated performance on your Porsche Boxster or Cayman 981 with the STRATEC Catless Performance Exhaust Manifold Headers, engineered to eliminate factory catalytic restrictions and maximize exhaust flow.

Designed for the 981 flat‑six platform, these race headers replace the restrictive OEM manifolds to improve exhaust scavenging, reduce backpressure, and free up horsepower across the mid‑range and top end. Expect quicker revving, stronger acceleration, and a louder, more aggressive motorsport exhaust character.

Precision fabricated from high‑grade stainless steel with mandrel‑bent runners and TIG‑welded construction, this STRATEC system installs directly to factory mounting points for clean bolt‑on fitment.
