Why Upgrade to a Dual Exhaust System?

1. Increased Performance: An upgraded dual exhaust system often features larger diameter pipes, smoother mandrel bends, and less restrictive catalytic converters, allowing for a freer flow of exhaust gases. This results in improved horsepower and torque, enhancing overall performance and responsiveness. Reduced backpressure allows the engine to breathe better, translating into quicker acceleration and higher top speeds.

2. Improved Sound Profile: One of the most noticeable changes comes in the form of a deeper, richer exhaust note. Customizable mufflers and resonators allow you to tune the sound to your preference – from a subtle, refined growl to a full-bodied roar that announces your arrival.

3. Weight Reduction: High-quality aftermarket exhaust systems are often lighter than stock, thanks to the use of lightweight materials like titanium or stainless steel. Reducing unsprung weight at the rear of the vehicle can positively impact handling and braking performance.

4. Aesthetic Appeal: Dual exhaust systems often feature larger, more aggressive tailpipes that add a sporty touch to the Cayman’s rear end. Sleek designs and polished finishes not only improve the visual appeal but also communicate the enhanced performance capabilities.

Exploring Your Options

When considering a dual exhaust upgrade for your Porsche Cayman, there are several factors to contemplate:

Materials: Stainless steel is popular due to its durability and resistance to corrosion, while titanium offers extreme lightness but comes at a premium price point.

Brand and Quality: Choose reputable brands known for crafting exhausts specifically for Porsche models. Names like Akrapovič, Fabspeed Motorsport, B&B (Billy Boat), and Eisenmann are known for their precision engineering and compatibility with OE fitment.

Cat-back vs. Header-Back: Cat-back systems replace the exhaust from the catalytic converter back, whereas header-back systems replace everything from the headers down. A header-back system generally offers greater performance gains but is more involved and expensive.

Valvetronic Technology: Some high-end exhausts come with valvetronic systems that allow drivers to switch between quiet mode for daily driving and a louder, more open setting for track days or spirited drives.

Installation Process and Legal Considerations

Installing a new dual exhaust system usually requires professional assistance due to the complexity of the job. It involves removing the old exhaust, welding or clamping on the new parts, and potentially recalibrating the ECU to optimize performance based on the new configuration. Always consult with a certified mechanic or Porsche specialist to ensure proper installation and avoid voiding any warranties.

Be aware that altering your exhaust system may affect local noise regulations and emissions standards. Check with your local DMV or governing agency to confirm compliance with legal requirements.


Upgrading your Porsche Cayman’s exhaust system to a high-performance dual setup is a significant step towards unlocking its full potential. It not only enhances the car’s auditory and visual presence but also contributes to improved power delivery and efficiency. However, it’s essential to choose wisely, taking into account factors such as material quality, brand reputation, and regulatory compliance. With careful planning and execution, your Cayman can reach new heights of performance while retaining its signature style and sophistication.

Remember, every modification should be approached with the intent to enhance your driving pleasure responsibly, respecting the engineering excellence that Porsche has built into each Cayman model.
