DEVELOPMENT:  Our goal was to offer a valved exhaust that delivers a refined cabin presence.

It is easy to increase the volume of the 718, but a challenge to bring out a more aggressive note while making the flat four sound distinctly Porsche which is a common complaint.

The turbo and large amount of sound deadening in the 718 do a great job of keeping the cabin calm, but raising the volume to compensate can bring out negative notes in the exhaust such as rasp and drone.

SOUL applied the same design principles as their renowned valved exhaust line for previous Boxster / Cayman generations to deliver a refined increase in sound that pairs well with a free flowing down pipe to yield an exhaust note that isn't overbearing.

This is a superior option for cars not equipped with the Porsche Sport Exhaust from the factory. 

The HJS HD 200 cell catalytic converter and smooth mandrel bent piping ranging from 90mm down to 55mm encourage better throttle response and an exciting exhaust note.

Easy to bolt in with no modifications required, this is a great, reversible solution to make your Boxster or Cayman more exciting.


CONSTRUCTION:  Each system is made from mandrel bent T304L stainless steel tubing (featuring 2.5″ OD over axle pipes) and features mufflers with fortified casings in the interest of durability. 

With the valves closed the exhaust gasses are routed into the SOUL muffler, which is packed with high quality sound deadening material designed to withstand abuse and not blow out over time.

The mufflers are incredibly effective at minimizing drone.

Exhaust gases make their way through the muffler and out through perforations into the outer piping. 

With the valves open, exhaust gases are now free to exit through large 2.5″ piping while perforations allow exhaust gasses to “talk” with the muffler, encouraging a fuller, more robust tone.

 Each down pipe is assembled out of mandrel bent, thick wall T304L stainless steel, then rigorously quality checked. Back purged TIG welding ensures proper weld penetration and longevity.


SOUND: Experience refined aggression.

The overall exhaust note is much sharper and the turbos make themselves known.

With valves closed, you can carry on a phone conversation on the highway without any intrusion from the exhaust.

The exhaust offers a respectable level of snarling and crackling while effectively minimizing drone at all RPM and throttle loads.

Sport mode unleashes an increase in crackles and burbles.


VALVE OPERATION: A valve controller is included with every system and is required for non-PSE cars.

PSE equipped cars will retain full factory functionality by using the factory vacuum lines.

The valve controller is optional for PSE equipped cars and allows full valve control at all times.

Valve functionality can be controlled by the factory PSE button, included valve controller fobs, or with HomeLink buttons.


BOLT ON AND GO:  Each component is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition.

Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.


CHECK ENGINE LIGHT?:  This product may trigger a check engine light due to removal of the factory catalytic converter.


+  This product is not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road use only due to removal of factory catalytic converters

+  Boost spikes can occur as a result of increasing the exhaust flow with a catless downpipe. We highly recommend an ECU tune to not only extract maximum power from this mod, but to have the best possible drivability as well.


Add a BMC high flow air filter for even more sound and response.
