SOUL | 718 GT4 / GTS / Spyder Valved Exhaust

With two distinct tones, SOUL’s Valved Exhaust offers a significant sound improvement over factory PSE through a bespoke X-pipe muffler and anti-drone design features. Valves open mode elicits a smooth, sporty GT3-like tone for an invigorating driving experience. Valves closed mode calms down the volume for refined cruising with just enough presence to be appreciated. Engineered to pair well and not be overbearing with other aftermarket mods like over axle pipes and headers.
+ Fits all Porsche 718 GT4 / Spyder / GTS 4.0L vehicles (2020+) in North America. European vehicles use a different mounting style than North American vehicles. Contact us for a European conversion kit.
+ Weighs approximately the same as OEM PSE (37 lbs)
+ All Soul Performance Products exhaust components are backed by the industry’s first and finest Lifetime Warranty for both street and track use
DEVELOPMENT GOALS
- Improve upon the factory design and achieve a throatier / smoother / higher pitched tone.
- Increase the presence and character of the exhaust note in the cabin while maintaining a reasonable level of resonance / drone while driving in both the valves closed and open modes through our signature drone fighting capabilities.
- Offer the ability to notably reduce the sound level of the car outside to fly under the radar when necessary.
- Achieve an effective delta in sound between both modes for two usable, well engineered experiences - mild and wild.
DRIVING IMPRESSIONS
Changing just the PSE muffler with stock over axle pipes offers a superb change in tone. It is smoother and higher pitched, more in line with the flat 6 character we’ve come to appreciate with previous generations of Boxster / Cayman. The PSE running valves closed had no real tone to it, we’d describe it as tinny, hollow, and rather boring as you can hear more of the intake than the exhaust. With our Valved Exhaust System the exhaust now has real character, and you can hear more of it everywhere with valves open and closed. Expect a smooth transition between valves closed and open modes. With the rest of the exhaust stock, the overall sound level at WOT with valves open may not sound dramatically increased. This is due to how aggressive the flow path is with valves open on the new 718’s PSE muffler. However, on our system the larger tubing diameter, distance traveled, and blending of the X-pipe gives the sound more depth and changes the tone to a smooth / higher pitch song. It sounds incredible especially from the outside, offering a true sporty note one would expect from the high end 4.0L.
We found that the particulate filters in the over axle pipes put a big damper on the overall sound level and how it carries into the cabin. Think of it like a cork in the middle of the exhaust, letting a PSE muffler replacement tease you but not giving you the full experience. Combining our Valved Exhaust System with our Competition Over Axle Pipes is when the skies open up, the sun shines down and the Porsche Gods have blessed us with the sound we’ve all been waiting for. Inside and outside the car, windows up and down, the experience is nothing short of transformational. At wide open throttle it sounds like a weapons grade symphony. Very reminiscent of a GT3 at 9k, and arguably better than any stock GT3 you’ll ever hear on the street. Ditching the factory over axle pipes finally allows the car to have some burble on deceleration but nothing too over the top, just enough and just right. When you do a hard shift, a visceral crack erupts to really put a smile on your face. Not like a shotgun blast going off, more like a reward for actually driving the car how it’s meant to be driven. The sound is aggressive, but not overly so like you just took an RSR off the track for street shenanigans. When you’re off throttle cruising around, it’s relatively docile and comfortable (that secondary flow path at work). If you want to fly under the radar and significantly cut down on sound level outside the car, you simply close the valves and away you go in stealth mode. However, even with valves closed the tone and character of the exhaust is still there, not dead muted like the PSE muffler. It has cabin presence, some ever so mild drone/resonance in low rpms that we consider quite reasonable compared to the other configurations we’ve tested - even with valves open it’s quite reasonable. We’d almost say it’s more a character of the system and it’d be a shame if there wasn’t any to tease you into squeezing on the gas to hear more of it. We highly recommend installing a SOUL Valve Controller Kit to override the PSE programming at your convenience, and hear what it has to offer under 4-5k rpm in the first few gears - it’s worth it!

By far the best sounding aftermarket exhaust for GT4/Spyder; I'll buy one for the soul purpose of getting this.

[@SoulPerformanceProducts]

Thank you!!! I see what you did there! :) - Mike

[@stnford6051]

Music to my ears. Hands down the best sounding exhaust system, it adds to the overall aesthetic 718 Spyder. A guaranteed purchase.

[@SoulPerformanceProducts]

Thank you! We put a lot of effort into tuning the tone of this system and we appreciate that it caught your attention! - Mike

[@gnrrpreacher]

So much love!

[@SoulPerformanceProducts]

Thank you! - Mike

Soul valve control is the very first mod everybody should get. That alone makes a huge difference and if you’re ready to get an exhaust system, soul is the best for the buck and it sounds awesome! I’m very happy with their products and their customer service is really top notch! Some of my friends in toronto also use their products and they are also very happy...

[@SoulPerformanceProducts]

Thank you for the kind words, glad to hear you're happy! - Mike

[@jortepap]

perfect exhaust.

[@SoulPerformanceProducts]

Thank you, cheers! -Mike

Holy hell that sounds good. Was about to order OAPs but now thinking the valves exhaust may do the trick by itself. How does the valves exhaust with valves open and stock OAPs sound compared to stock OAPs and the non-valved race exhaust?

[@SoulPerformanceProducts]

Thank you! The Race Exhaust includes bespoke OAP's with single pipe inlets instead of dual like factory making it a complete 2.5" system. The Valved Exhaust will offer a more sophisticated tone as even with valves open you get blending with the muffler and internal X-pipe. Volume of the Race Exhaust is much more aggressive and the resonators are primary to cut down on rasp as to not make the tone too harsh. Race Exhaust would be too aggressive for most people looking for a streetable daily driven car. -Mike

[@ylisuarez2351]

Can you guys make a video with the Race exhaust and Comp headers pls. Also should that combo change the pitch/tone of the exhaust to a more GT3 high pitch sound or should I go with this valved exhaust adding Comp OAP and Comp Headers? Thank u

[@ylisuarez2351]

I’m coming from an F80 M3 with catless down pipes and non resonated valveless exhaust so I’m used to really loud😂

[@SoulPerformanceProducts]

@@ylisuarez2351 The Race Exhaust paired with Competition Headers are very, very loud - there would be no sound attenuation devices in place. At this time. Rear exhaust choice depends on if you want valve functionality or not. If you did the Valved Exhaust, headers, and overaxle pipes you would still be able to quiet the car down just a bit. -Mike

[@jonathanbarker8584]

Is this video shot with stock everything except the swap out for the new Soul valves exhaust ? Thanks J

[@SoulPerformanceProducts]

This setup is just our Valved Exhaust and Valve Controller Kit. -Mike

[@CS21dude]

If you were looking to improve tone only, and not add volume, and you only wanted to change one thing, would you do this or the OAP’s?

[@SoulPerformanceProducts]

Valved Exhaust will yield a more race inspired, smoother, higher pitched tone. OAP would add more response as you are deleting a filter, but it would just add loudness.

[@CS21dude]

@@SoulPerformanceProducts thanks for the reply, not many seem to start with the rear section - I think I would start there as I would not want it any (or much) louder. It seems like they didn’t mix the exhaust banks on purpose, perhaps for sound regulations or perhaps to help small exhaust companies stay busy 🤓

[@slyphendrivevlog8765]

was this paired with an aftermarket OAP?

[@SlickxAc]

Does the exhaust use the stock valve controller?

[@SoulPerformanceProducts]

It functions like factory - a valve controller to allow you to fully open the valves at all times is optional. -Mike

[@sassdachap4811]

Is this just with the x-pipe with the stock over axle?

[@SoulPerformanceProducts]

This is just our Valved Exhaust - stock over axle pipes. - Mike

[@CS21dude]

Valve controller enabled?

[@SoulPerformanceProducts]

@@CS21dude for this video, yes.
