DEVELOPMENT:  We sought out to maximize performance and boost response while minding clearance on daily driven cars. Our optimized 3 into 1 merge collector design improves response over the poor factory design, while our runners ultimately increase exhaust velocity into the collector and turbo. Looking into the factory headers you will notice a support in the middle runner which is detrimental to a smooth flow path out of that exhaust port – all in all the design is very basic with lots of room for improvement. The factory turbo inlet measures around 1.54” ID and we sized our header outlet to 1.63” for a smooth flow path into the turbo. The internal volume of the header combined with the resulting design improvements pairs well with the efficiency map of the turbo giving you noticeably quicker boost response and more power throughout the RPM range. Pushing the gas pedal down commands faster feedback from the car and each gear has more usable power before a downshift.

The factory header utilizes a double wall design while our design is single wall yielding in a more pleasing, sharper edge to the exhaust and increased turbo sound. Exhaust volume and tone quality are delightfully increased without yielding drone or undesirable qualities. Expect more burbles and sharper pops between shifts and on deceleration.

POWER: Below are the real, unedited, straight from the Mustang dyno results as conducted by Apex Autoworks with before and after runs on a Base model Carrera already equipped with SOUL Sport Catalytic Converters and SOUL Performance Exhaust with COBB Accessport Stage 2 Map. This dyno chart is made of the average performing charts of 3 before and 6 after runs. Max power gains of 12 whp and 20 ft-lbs come in quickly and hold until redline for a noticeable increase in driving performance. A custom Pro Tune would further take advantage of the increased flow and unlock greater gains.

CONSTRUCTION:  Each set is assembled in house in the USA out of laser cut flanges and mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity. We fabricate these headers using thick gauge aluminum fixtures which act as a great heat sink during the welding process and prevent warping not only of our products, but the fixtures themselves to ensure perfect fitment.

BOLT ON AND GO:  Every component is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure they arrive in perfect condition. New high grade hardware and OEM Porsche gaskets are included for installation.

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.

    I just picked the car up. SUPER happy with the results. I was able to take it through all phases of listening to the exhaust from non-sport, sport and sport+ and windows up/down and sunroof flipped.

    1. Non-sport with the windows up sounds just like stock, maybe a little more noise when you get on it. I tried to emulate the scenario of the family being in the car and holding a conversation. No problem at all = perfect.
    2. Sport windows up or down – holy crap crackles and pops! I thought there were a lot before. It is super aggressive and they are LOUD! It pops loud between shifts even. If this is what you’re looking for, you will not be disappointed.
    3. Sport+ windows up gives you a very nice sound that fills the cabin. Makes the car feel more special as it adds to the theater of driving a great car. Windows down – more of the same. You can really hear the car nicely and the decel sounds so great and crisp.
    4. Sunroof tilted up – Allows you to hear the turbo spool up a bit more than with the stock exhaust. I like driving around with the sunroof tilted like this. Gives you a bit more sound inside and not too much wind noise like the window completely open.
    5. Windows down half-way – both in sport and sport+ allows you to hear what’s going on outside the car without all the wind noise. You can really tell the car is much louder outside than what you hear inside. The pops in sport mode are very loud.
    At WOT, the sound is perfect. It’s exactly what I’m looking for. LOVE IT!!!
