Description

DEVELOPMENT:  Would it be a GT4 exhaust suite without upgrades for the track enthusiasts?  We redesigned the entire exhaust aft of the headers for maximum flow. The factory dual exit/entry flanges connecting the over axle pipes to the PSE muffler limits the piping diameter to 2.25”. The SOUL Race Exhaust System is optimized into a single 2.5″ flow path on either side with accommodations to mount factory style tips. Great care was made to mind clearances for hard use on and off the track, expect no issues with our mandrel bent piping. The longer piping routing also helps noticeably smooth out the exhaust sound while the slight blending of the X gives the car a higher pitched sound more akin to the previous 981 generation we’ve come to know and love. Durable race resonators add a more refined note to the aggressive exhaust note while slightly reducing drone. A non-resonated version is option for those looking for maximum weight reduction and sound.

POWER: Below are the unedited, straight from the Dyno Jet dyno results as conducted by Jotech Motorsports with before and after runs on a 718 GT4. Max power gains of 30.7 whp and 16.1 ft-lbs of torque come in quickly and hold until redline for a noticeable increase in driving performance. An ECU tune would further take advantage of the increased flow and unlock greater gains.

CONSTRUCTION:  Each system is assembled in house in the USA out of mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity. Water jet cut flanges are made to ISO 9001:2015 standards with tolerances of +/- 0.003 inches for extreme precision. We fabricate these over axle pipes 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 four 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.

    Got my Soul Race Exhaust (with resonators) installed over the weekend on my 718 Spyder (1K miles) and got a few different types of drives in yesterday and today to get some initial impressions. First off, WOW what a difference! Sound is amazing and makes the car so much more fun, even just cruising around town. Definitely louder but what I love the most is the higher pitch scream that reminds me more of a 991.1 and 991.2 GT3…not quite there of course but definitely a step in the right direction. Gives the car much more attitude and I find myself driving way more aggressively. Proper GT sound and, from what I can tell, a slight improvement in performance. Thank you John. Great work.

    Now, there are a few small drawbacks to note but, for me, they are worth the price of admission. First off, there is definitely a drone at 2K to about 2.7K RPM when getting on the gas. If you are very sensitive to drone, be warned it’s there. One thing to note, there is much less drone with the top down. Another draw back is the install….it’s nothing too difficult but it is time consuming since you have to jack up the car to get underneath access and also have to take the rear wheels off to be able to get easy access to the bolts to the header/link pipes. Lots of bolts, nuts, and screws to deal with. Having a quickjack would have definitely helped to speed things along. Conventional jack and jack stands were a pain to set up properly.

    In summary, I’m happy with the exhaust as it definitely adds more fun to the experience….especially with the top down. Great value at $2500 when compared to other alternatives.
