9m Sports Stainless Steel Valved Silencer 

Upgrade the sound and character of your Porsche 987 Boxster or Cayman with the 9m Sports Stainless Steel Valved Silencer. The valved design gives the driver control over the exhaust character at the push of a button, allowing you to switch between a quieter exhaust note and a louder, more sporting tone. 9m also specifies a noticeable improvement in sports car sound and throttle response.

Fits:

• Porsche Boxster 987 2.7L 2005-08/08
• Porsche Boxster 987 S 3.2/3.4L 2005-08/08
• Porsche Cayman 2.7L 987C 2006-08
• Porsche Cayman S 3.4L 987C 2005-08

Manufactured from precision-welded 304-grade stainless steel, the system is designed as a direct replacement for the original Porsche rear silencer, with no cutting or welding required.

What Does the Valved Exhaust Do?

The exhaust valves alter the path of the exhaust gases through the silencer. This allows the system to provide a more subdued sound when required and a more pronounced sports exhaust note when the valves are opened.

This makes it particularly suitable for a road-going Porsche where you may want a quieter exhaust during normal driving while retaining the option of a more engaging sound when desired.

Why Upgrade?

The factory exhaust is designed to balance refinement, noise regulations and performance. For owners looking for greater exhaust character, the 9m valved silencer provides additional sound without permanently committing the car to a louder exhaust note.

The X-pipe-style system also gives the rear of the car a more purposeful appearance, with a choice of black or silver slash-cut exhaust tips.

Direct Bolt-On Installation

The 9m system is designed to replace the OEM muffler using a direct bolt-on installation, requiring no cutting or welding. This makes it a straightforward exhaust upgrade without unnecessary modification to the vehicle.

9m states that the silencer complies with emissions regulations and does not trigger the Check Engine Light.
