Description

Many owners are underwhelmed with their 991.1 Carrera’s sport exhaust sound and performance – it’s just not enough. We’ve set out to create an exhaust with a true Jekyll and Hyde personality that matches perfectly with the persona of the Carrera – a wolf in sheep’s clothing. Our first priority was to design the system so that with 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:  Our 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 – like our Long Tube Street 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. Our goal was to filter out the undesirable frequencies in that range while smoothing the valves closed to open transition on factory PSE equipped cars.

Our 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 exhaust 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.

BOLT ON AND GO:  Each exhaust is tested in a fixture to ensure perfect fitment and then foam packed to arrive in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts. New high grade hardware is included. This system works seamlessly with the factory PSE controls but can also be used on non PSE equipped S / GTS cars by installing a SOUL valve controller kit.

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 issues or answer any questions that you may have.

NOTE:  Installation of the valve controller on non-PSE models is more difficult than on PSE equipped vehicles due to wiring (power source must be located and tapped) and vacuum lines needing to be installed. Rear bumper must be removed. We highly recommend professional installation, for recommendation of your nearest SOUL installer please contact us.

    In summary:
    The sound is exactly what I was looking for. Much more aggressive over factory PSE exhaust. Quiet with valved closed while cruising.
    No droning whatsoever when cruising below 3400 RPM with valve closed.
    Works perfectly with factory PSE option. Why wouldn’t it. ☺
    High quality craftsmanship and perfect fitment.
    Did I mention the sound is amazing?

    I had my Valved Performance exhaust and chromed tips installed today and all I can say is wow! It sounds amazing and is border line too loud. Good thing for the valved exhaust part. I drove it about 15 miles after picking up my car and liked the snap, crackle and pop. One of the things I really missed about my GT350 was the sound of the exhaust scream of the FPC V8 and while not the same this exhaust closes the gap considerably. I debated having custom tips done in Jet-Hot with either a titanium or platinum finish but with the way my car is setup I think the chrome matches fine. The shop that did the install is https://www.salernomotorsports.com/. They have an excellent reputation locally and work on a lot of Porsche’s and Ferrari’s. They had never installed a Soul exhaust before but they were very impressed with the construction quality, ease of installation and the sound.

    New exhaust and a clean car. Every neighbor is looking at me as I pass by and are like Wow….
    Thank you for providing the sound this car should have.

    I completed my DIY install on my 2013 CS with PSE. Removal of the stock exhaust, installing new air filters, and prepping for new installation took about two hours. Installing the new system took another 3-4 hours and went pretty smoothly. The exhaust sounds amazing and it’s a complete monster with valves open. I love it!

    ok, so I got mine installed today….OMG, the sound from first into second at 6Kish, was magical..reminds me of the F1 cars back in the day! My MPG is going to hurt, on ramps and any chance to hear that quick PDK shift at 6Kish..OMG
    What have I done? Its Ginger when you push the PSE button on and Mary-Ann when its off.

    Really well money spent!

    Replaced the stock PSE exhaust on my 991.1 Carrera S with the Soul Performance valved exhaust and couldn’t be happier. It took the stock exhaust which already sounded good and amped it up to a level 10, while keeping that Porsche flat six sound. Much much louder cracks and pops on downshift with the valves open and just a little louder than stock with them closed. There’s NO drone at all which I was worried about.

    The exhaust arrived very well packed and it’s so much smaller and lighter than stock. Installation was straightforward and everything fit flawlessly. It’s just a shame it’s all hidden under my Porsche with only the larger black chrome tips showing, but once the engine is cranked and the rumble begins you know it’s not stock 😂. My first test run down the interstate and I had several thumbs up from other car guys.

    I’m looking forward to adding the headers next and maximizing the sound and power gains along with a tune!

    This is how the 911 should sound from the factory!

    Installed. One week in…….love it. Spectacular. Absolutely love it.

    Couldn’t be happier with my purchase or the support. Sounds amazing and adds that extra something my little 991 base was missing. Highly recommend – the build quality and sound is perfect. EUROTECH in Natick handled install – great work all around.
