CEES High-Performance Exhaust Headers for Porsche 911 (997.1) Carrera / Carrera S
Unleash the iconic flat-six exhaust rumble and maximize exhaust gas velocity on your Porsche 911 (997.1) Carrera. Precision engineered from mandrel-bent aerospace-grade T304 stainless steel, CEES high-flow 3-into-1 performance headers feature smooth, free-flowing primary runners and high-efficiency merge collectors designed to eliminate exhaust backpressure, sharpen throttle response, and extract peak performance across the RPM band.
🚀 Engineering Highlights
- High-Flow 3-into-1 Runner Design: Engineered with smooth mandrel-bent primary tubes to maximize exhaust scavenging and reduce cylinder backpressure, improving low-to-mid range torque and throttle sensitivity.
- Smooth Merge Collectors: Precision-fabricated merge collectors provide a smooth transition for exhaust pulses entering the catalytic crossover sections, minimizing turbulence.
- T304 Stainless Steel: Handcrafted with robust CNC-machined flanges and back-purged TIG welds for lifetime structural durability against extreme heat cycling and track use.
- Aggressive Flat-Six Exhaust Note: Amplifies the raw, throaty Porsche boxer tone under acceleration while maintaining a clean, drone-free cabin environment during cruising.
- 3D Laser-Scanned OEM Fitment: 100% bolt-on replacement directly mating with OEM cylinder head ports and factory or aftermarket catalytic downpipe crossover sections.

FAQ
1. Will these headers fit both the 3.6L Carrera and 3.8L Carrera S?
Yes. The cylinder head exhaust port spacing and mounting bolt patterns are identical on both the M96.05 (3.6L) and M97.01 (3.8L) naturally aspirated engines across all 997.1 Carrera models.
2. Will installing these headers trigger a Check Engine Light (CEL)?
No. On the Porsche 997.1 Carrera, the primary catalytic converters and oxygen (O2) sensors are located downstream in the crossover cat pipes, not within the headers. Replacing the exhaust manifold headers preserves factory O2 sensor monitoring without throwing error codes.
3. Is cutting or welding required during installation?
No. 100% bolt-on installation allows a return to stock at any time. (Reuses factory outlets).
4. Are you a direct manufacturer?
Yes — CEES Exhaust is a direct manufacturer based in Guangdong, China. We laser-scan, bend, and TIG-weld every exhaust component in our factory with rigorous quality inspection.
