SOUL Valved Exhaust System. Porsche 981 Boxster / 981C Cayman (2013-2016)

Porsche 981 Boxster / 981C Cayman SOUL Valved Exhaust System

The factory exhaust system on the Porsche 981 Cayman and Boxster is bulky and restrictive, muting both performance and sound. The SOUL Valved Exhaust System is designed to free the car’s natural character by reducing weight and incorporating a precision valve system that delivers a dramatic transformation in responsiveness, tone, and driving enjoyment.
With the valves closed, the system produces a refined, sporty exhaust note with zero drone—perfect for comfortable daily driving and discreet neighborhood entries. Open the valves, and the flat-six engine comes alive with an intoxicating motorsport-inspired soundtrack, ideal for spirited back-road drives or track sessions.

DEWELOPMENT:
We wanted to be certain that our system offered a superior spectrum of sound – Cup car inspired with valves open but with a refined, no droning tone with valves closed. The SOUL mufflers practically eliminate droning – even with aftermarket headers the sound is reserved in the cabin with valves closed!

CONSTRUCTION:
Each system is constructed from mandrel-bent T304L stainless steel tubing, featuring 2.5″ over-axle pipes, and equipped with mufflers built with reinforced casings for long-term durability.
•  With the valves closed, exhaust gases are directed through SOUL’s high-quality mufflers, packed with premium sound-absorbing material engineered to withstand heavy use without breaking down. These mufflers are highly effective at eliminating drone, channeling gases through perforations into the outer piping for a smooth, refined tone.
•  Open the valves, and exhaust gases flow freely through the large 2.5″ straight-through piping, while the perforations allow the exhaust to interact with the muffler—producing a deeper, fuller, and more aggressive sound that captures the true character of the flat-six engine.

TIPS:
Choose from a variety of tip styles and finishes, ranging from sleek single-wall 321 stainless steel to premium double-wall chrome. For a personalized touch, logo engraving and custom tip colors are available upon request. For those seeking performance benefits, lightweight titanium single-wall tips are also offered—shedding nearly a pound compared to stainless steel options.

BOLT ON AND GO:
Each exhaust system undergoes rigorous quality checks and fixture testing to guarantee precise fitment. Every kit includes detailed installation instructions, making the process straightforward for most DIY enthusiasts. Valve operation integrates seamlessly—controlled via the factory PSE button, included valve controller fobs, and even compatible with HomeLink for added convenience.

LIFETIME WARRANTY:
Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any questions or issues that you may have.
