Constructed from high-quality SS304 stainless steel, this system features advanced valved technology that allows you to customize your exhaust note, providing a perfect balance between daily comfort and exhilarating performance.
Key Features:
Material: Made from SS304 stainless steel, a premium material known for its excellent corrosion resistance, strength, and durability. This material ensures that the exhaust system can withstand high temperatures and harsh driving conditions while maintaining its appearance and performance over time.
Valved Design: Incorporates integrated exhaust valves that allow you to control the exhaust sound. The system enables you to switch between a quieter, refined exhaust note for everyday driving and a more aggressive, louder tone for spirited driving or track use. This flexibility ensures a customizable driving experience that suits different driving scenarios.
Cat-Back System: This full cat-back exhaust system includes all components from the catalytic converters to the exhaust tips. This comprehensive upgrade ensures improved exhaust flow and performance throughout the entire system, optimizing engine efficiency and power.
Performance Enhancement: The high-flow design of the valved cat-back system reduces back pressure and improves exhaust gas evacuation. This leads to increased horsepower and torque, enhanced throttle response, and faster acceleration, maximizing the performance potential of your Porsche 911 Carrera 991.1.
Sound Quality: Delivers an engaging and dynamic exhaust note that complements the 3.8L engine of the 911 Carrera 991.1. The valved design allows for a more aggressive and resonant sound when desired, while also providing a quieter, more refined tone for everyday driving.
Design and Finish: Features polished or matte stainless steel exhaust tips that add a high-end, aggressive look to the rear of your Porsche 911 Carrera. The design integrates seamlessly with the vehicle’s styling, offering a visually striking element that highlights the performance upgrades.
Fitment: Engineered to ensure a precise fit for the Porsche 911 Carrera 991.1 3.8L without the need for modifications. The system includes all necessary mounting hardware and brackets for a straightforward installation.
Durability: SS304 stainless steel’s natural resistance to high temperatures and corrosion ensures long-lasting reliability. This durability guarantees that the exhaust system performs well and retains its appearance over time.
Installation Tips:
Preparation: Lift and securely support the vehicle. Gather all necessary tools and ensure you have the complete Valved Performance Exhaust Cat-Back System, including the exhaust components and mounting hardware.
Removal: Carefully remove the stock cat-back exhaust system by detaching it from the catalytic converters and any supporting brackets. Keep track of the original setup for reference during installation.
Installation: Position the new Valved Performance Exhaust Cat-Back System in place, aligning it with the existing mounting points. Attach the system using the provided hardware and brackets, ensuring all connections are securely fastened.
Fitment Check: Adjust the alignment of the exhaust tips for optimal fit and appearance. Ensure there are no clearance issues or misalignments, and make any necessary adjustments.
Testing: Start the engine and operate the exhaust valves to test the different sound profiles. Listen for any unusual noises or exhaust leaks and ensure that all connections are secure.
Final Inspection: Conduct a thorough inspection of the installation to ensure everything is properly mounted and functioning. Verify that the performance gains and sound enhancements meet your expectations.
Additional Considerations:
Professional Installation: Although the installation process can be straightforward, professional installation is recommended to ensure precise fitment and proper function of the exhaust valves.
Emissions Compliance: Verify local emissions regulations to ensure that the new exhaust system complies with regional laws. Modifications to the exhaust system can affect emissions compliance depending on your location.
