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.
• Fits all Porsche 981 Boxster / Cayman models (2013–2016)
• Direct bolt-on installation with included instructions
• Choice of multiple exhaust tip styles and finishes—or customize your own
• Valve controller kit included – necessary for cars without PSE and optional for cars with PSE to provide manual valve override
• Covered by SOUL’s Lifetime Warranty for street and track use
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.

RACETRACK USE ONLY:
SOUND: TUBI SOUND
Tubi Sound is the standard sound of Tubi Style exhausts, louder and more powerful than the original sound. This sound represents our brand.
The kit includes the right and left-hand mufflers without valve. It can be assembled on the OE central silencer, or in combination with the Tubi Style central silencer.
The component is perfectly interchangeable with the original components, following the instructions in the constructor's workshop manual.
EXHAUST VALVE: NO VALVE
The exhaust system does not include a valve and always guarantees the most impressive sound. If the standard system includes one, control of the exhaust valve by both the engine ECU and by the driver via the specific control systems is no longer possible.
The muffler must be used in conjunction with the original exhaust end tips.
END TIPS DESIGN OE
The muffler must be used in conjunction with the original exhaust end tips.
MATERIAL
AISI 304 STAINLESS STEEL
A choice stainless steel ideal for aggressive environments where combustion emissions can cause serious chemical corrosion on other types of metal.

RACETRACK USE ONLY
These components are designed and developed for racetrack use and to maximise the car's performance. They are not street legal and must be installed by professionals in the sector
ECU REMAPPING - FOR PERFORMANCE
On turbo cars, catalytic converter replacement may modify turbocharger operating conditions and cause a deterioration of the torque delivery curve. To ensure full benefit from the new racing component, the engine's ECU must be reprogrammed to maximise performance. If the engine warning light comes on, the ECU must always be reprogrammed to eliminate it
SOUND - + RUMORE
The + Rumore variant delivers the original Tubi Sound timbre but with the highest possible volume
SYSTEM FINISH - POLISHED
Mirror finishes are highly reflective and created by polishing the stainless steel. The polishing process enhances appearance and consistency, making cleaning easier. A special rolling procedure is used. It is essential to remove deep scratches as any surface defects will be very noticeable on the finished product. it improves corrosion resistance. The polishing eradicates crevices where corrosive particles can lodge themselves
END TIPS NUMBER AND POSITION - 2 + 2 CENTRAL
There are two pairs of tailpipes with a gap between them, in the centre of the rear bumper
MATERIAL - AISI 304 STAINLESS STEEL
A choice stainless steel ideal for aggressive environments where combustion emissions can cause serious chemical corrosion on other types of metal
REDUCED CELL CATALYTIC CONVERTER - 100 CELLS
Race catalytic converters have fewer cells than standard factory systems. This reduces exhaust back pressure while still maintaining the operation of the catalytic converter, and improves performance and sound
EXHAUST VALVE - ELECTRIC
The exhaust system is complete with electric valve. The electric actuator is not included and the standard actuator already installed on the car must be used. Control of the original valve is still provided
HEAT SHIELDING - INSULATED
Tubi Style ensures maximum protection for components in critical and dangerous positions by using insulation made with the same technology employed by car manufacturers
Please note: sports catalytic converters or bypass pipes do have type approval and may not be legally installed on vehicles manufactured after 1st March 2001. They can not be used on a public road and are not MOT compliant, they are designed for race and track cars only.
