DEVELOPMENT:  Following the success of our Valved Exhaust and its ability to fight drone, we wanted to offer a lighter, valveless version that offers an invigorating exhaust note (just like valves open mode on our Valved Exhaust) at all times with the least amount of undesirable elements like droning and rasp. This system is perfect for those who crave an aggressive sound to pair with aftermarket headers and not have it be overbearingly loud. The volume level is delightfully greater than that of PSE (Porsche Sport Exhaust) with valves open while retaining a refined exhaust note. This system is also beneficial for track cars looking for maximum flow in an exhaust but must mind decibel readings. The mufflers are incredibly effective at minimizing drone and encourage a fuller, more robust tone befitting of a Porsche.

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. The SOUL mufflers are packed with high quality sound deadening material designed to withstand abuse and not blow out over time. Choose from a variety of 321 stainless exhaust tips in different styles and finishes – or contact us to customize your own set! Titanium single wall tips are also available and save nearly a pound of weight over stainless steel tips!

BOLT ON AND GO:  Each exhaust 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.

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.

    Installed the Soul Performance 981 Performance (so non-valved) exhaust last week – so – now it has about – week on it figured I would do a review. I’m a 2013 981 Base with 6MT and Sport Chrono – and the car has 11k miles on it.

    Install: The exhaust itself was a breeze, once I got to the actual installation. However, the removal of the original was a bastard. Amazing the corrosion on a car with only 11k miles on it. And – the studs are pressed into the header flanges, and had to be removed for the install. Heated the studs with a butane torch for 5 mins (each), and they came out with a few whacks. Also, the exhaust bracket clamps needed replacing (cheap part), but no one had them so that put a damper on the install. Ended up using some hose clamps temporarily until the new clamps came from Suncoast. Once the prep work was done, I had the new exhaust on in less than an hour.

    Fit and Finish: Amazing. The stainless matte finish that Soul uses is gorgeous. Love the texture and matte finish – and it handles prints, etc well also. The fit of the exhaust was top notch – oem quality overall how well it went right on.

    Sound – Can I get a ‘Hell Yes!” Sounds unreal. I opted not to go for the valves, well, why? To me I don’t have PSE currently, and it doesn’t integrate, so why have an extra button? And – why not sound like a sports car all of the time, was my thought process.

    The sound on cold start and acceleration are out of this world, and make that flat 6 sound like it ought to. Minimal drone for what the exhaust is (yes, there is some, but it is not excessive at all).

    And – call me crazy – but in Sport Plus – it absolutely snaps-crackles-and pops more than it does in ‘normal’ mode. Not sure if that is because the engine maps differently in Sport plus and Sport as opposed to normal (can anyone confirm?) – but – it DEFINITELY makes a difference. It is definitely not in my head that Sport Plus changes the dynamic of the exhaust, even though no PSE.

    Overall, great product.
