Frequently Asked Questions
Unlock maximum naturally‑aspirated performance from your Porsche 718 4.0L platform with the STRATEC Catless Performance Exhaust Manifold Headers, engineered to eliminate factory catalytic restrictions and dramatically improve exhaust flow.
Designed for the 4.0L flat‑six engines found in the 718 Spyder, GTS 4.0, and GT4, these race headers reduce backpressure, enhance exhaust scavenging, and deliver sharper throttle response with stronger mid‑range and top‑end power. Expect quicker revving, louder volume, and a raw motorsport flat‑six sound.
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.
