SOUL's  991.1 Carrera Valved Performance Exhaust System has been designed with the professional enthusiast in mind.

With valves open exhaust gases are free to exit through a completely unrestricted path out the tips offering a flat six symphony with a tone that will raise the hairs on the back of your neck.

On your way to pick up a client or heading out to dinner with someone special?

Keep the valves in closed position and enjoy a refined low key tone as the factory side mufflers do their job quite well.

If you’re worried about drone on your PDK equipped car, this system has little to no drone. 

Street Headers are built around free flowing HJS HD 200-cell catalytic converters and long tube runners for maximum gains in power, throttle response, and flat-six engine tone.



+  Fits all Porsche 991.1 Carrera Base models without PSE only (2012-2016)

 Valves are controlled with included valve controller and optionally, HomeLink controls

All Soul Performance Products exhaust components are backed by a renowned lifetime warranty for both street and track use.

Many owners are underwhelmed with their 991.1 Carrera’s sport exhaust sound and performance, it’s just not enough.

SOUL set out to create an exhaust with a true Jekyll and Hyde personality that matches perfectly with the persona of the Carrera.

The first priority was to design the system so that with the valves open, exhaust gases would have a straight flow path.

By using a larger tubing diameter, smooth radius bends and proper X-pipe crossover flow characteristics (improving exhaust scavaging effects, leading to increased volumetric efficiency), our system improves throttle response and performance drastically over the restrictive factory sport exhaust.


DEVELOPMENT AND TESTING:  The aim was to refine the level of daily driving comfort without sacrificing the race inspired tone and straight-through exhaust design.

A larger resonator would not yield the results we are looking for while requiring some revisions for clearances – this could compromise the high flow design principles of our exhaust.

Adding higher flowing aftermarket headers, to an aggressive rear system without proper sound attenuating features could result in a overly loud, possibly unpleasant driving experience.

Nearly 40% of our customers paired their rear exhaust with upgraded headers making it imperative that we consider such a configuration and engineer the exhaust appropriately.

Helmholtz resonators (also known as anti-drone tubes) are an effective way to reduce undesirable frequencies when engineered and utilized correctly. 

The 991.1 Carrera has an inherent 3,000-3,500 RPM range where drone can present itself when you add higher flowing exhaust components.

A goal was to filter out the undesirable frequencies in that range while smoothing the valves closed to open transition on factory PSE equipped cars.

The Long Tube Street Headers increase volume to an enjoyable level while adding more response and power to turn your Porsche into a true drivers car.

For the base model, we devised a solution to allow for retaining the factory side mufflers – simply cut the factory side mufflers and clamp on the included secondary pipes which connect the side mufflers to the exhaust tips.

Soul's final design has proved to offer the very best results on this application and achieved our high standards for sound quality and drivability.

 The math can be done to create the Helmholtz resonators – but how you incorporate them into your design makes a big difference.

SOUND:  The sound is aggressive – a primary benefit of our system is that with valves open there is straight, unrestricted path from the 2.5″ piping to the tips – but we’ve effectively massaged extra refinement into the system to match the premium experience that embodies all things Porsche.

With valves both open and closed the X-pipe helps smooth the sound even further. All in all, we’re very happy with the results and we’re sure you will be too.

With valves open, the free flowing nature of the system allows for a Cup car inspired sound – greater volume with a greater amount of crackles and burbles on deceleration.  

This system is for those who want added aggression at the press of a button. With valves closed the tone is very reasonable and refined, drone is kept to a minimum while still allowing for the flat six sound to be heard.


CONSTRUCTION:  Each 991.1 Carrera component is built in house out of mandrel bent, thick wall .065″” T304L stainless steel, then rigorously quality checked.

Back purged TIG welding ensures proper weld penetration and longevity.

Merge spikes are incorporated into the headers to smooth exhaust flow into the collector and increase power.

Thick water jet cut flanges cut to ISO 9001:2015 standards ensure perfect fitment and product longevity.


HJS CATALYSTS:  The highest quality catalytic converters available, known for their industry leading flow and durability.

They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow – all without a check engine light.

The HD design uses premium triple foil winding for maximum strength.

The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse.

SOUL uses a large and appropriately sized catalyst to allow for maximum gains.



  • Installation of the valve controller requires removing rear bumper, locating and tapping a 12V switched power source, and installing vacuum lines.
  • We highly recommend professional installation for this Porsche exhaust system. 
  • Cutting of the factory side mufflers is required to incorporate included piping to tips.
