Porsche Cayenne 957 3.6 Valved Sport Catback Exhaust System(2007-2010)

Unleash Maximum Flow & VR6 Acoustic Power — CEES Porsche Cayenne 957 3.6 Valved Sport Catback Exhaust System

Transform the driving dynamics and acoustic presence of your SUV with the CEES Valved Sport Catback Exhaust System, engineered exclusively for the Porsche Cayenne 957 3.6 (2007–2010). Precision-crafted specifically for the 3.6L VR6 naturally aspirated engine platform, this catback exhaust combines mandrel-bent high-velocity tubing with your choice of integrated dual Vacuum Valves or Electronic Valves operated directly via our wireless remote key fobs. Seamlessly toggle between quiet, drone-free daily cruising and an aggressive, unrestricted high-rev VR6 sport roar under acceleration.

🚀 Engineering Highlights

• Dual Valve Control Technology (Electronic or Vacuum): Take complete command over your vehicle's soundtrack. Choose between high-precision Electronic Valves or heavy-duty Vacuum Valves, both seamlessly operated by our dedicated wireless remote key fob controllers. Open the valves to unleash maximum exhaust gas velocity and exhilarating VR6 acoustic tone, or close them for quiet, comfortable cruising.
• Optimized VR6 Catback Flow Dynamics: Engineered with smooth, high-velocity mandrel-bent piping to reduce exhaust backpressure downstream of the factory catalyst, improve exhaust gas evacuation, and enhance throttle responsiveness across the rev band.
• Track-Grade T304 Stainless Steel & Grade 5 Titanium: Handcrafted from premium heat-resistant T304 stainless steel or aerospace-grade Grade 5 titanium for maximum weight reduction, rapid heat dissipation, and long-lasting corrosion resistance.
• Precision Acoustic Tuning: Internal muffler packing and tuned acoustic chambers eliminate low-frequency highway cabin drone while delivering an exotic, crisp mechanical exhaust note when the valves open.
• 3D Laser-Scanned OEM Fitment: 100% bolt-on installation utilizing factory mounting points and exhaust hangers without requiring cutting or welding.

FAQ

1. How do the electronic and vacuum valves operate on the Porsche Cayenne 957 3.6?

We offer two valve control options: Vacuum Valves and Electronic Valves. Both configurations include our wireless remote control module. With a simple click of the handheld remote, you can toggle between quiet mode (routing exhaust gases through tuned silencer chambers for comfortable cruising) and sport mode (bypassing baffles for raw acoustic power and maximum exhaust flow).

2. What is the difference between T304 Stainless Steel and Grade 5 Titanium?

T304 Stainless Steel delivers proven durability, corrosion resistance, and a deep, powerful exhaust tone. Grade 5 Titanium offers extreme weight savings (over 40% lighter), superior heat dissipation, and a higher-pitched, exotic mechanical note.

3. Is cutting or welding required during installation?

No. The system is engineered to factory mounting locations and connects directly using standard exhaust clamps and factory hangers. 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 design, laser-scan, bend, and hand-weld every exhaust component in our factory with rigorous quality inspection.
