@22:45, the look of pride on John's face is priceless. The front-to-rear competition setup is the ultimate Dragon Slayer. Holy Sh*T!!!
What an awesome time collaborating with Miami Miles and Soul!!! Epic video!!

Thank you my friend. Appreciate you 🙏🏻
Wow this is an incredible video. So much effort has gone into testing out each configuration. Wealth of info for current and future 4rs owners. Thanks for uploading this superb video 👍👍
Happy you enjoyed it my friend. It was an epic collaboration
Now we need a comparison of competing brands
For those that want to look through all of the dyno sheets and data, here is the google drive link so you can look over everything with patience. I ended up keeping the catted OAP's, Competition headers, and the Valved rear section. Will be posting a video with my impressions soon and will swap the Catted OAP's for the resonated competition OAP's at a later date to see how the experience changes.

Great data, thanks!
@@ItsTrackTime Thank you for your comment.
This is an amazing collaboration video. Super hard core, passionate porsch-o-philes and engineering shops. Well done lads! 🤘🏻💪🏻
Thank you uncle Pete!!!!!!!!!
Came to see the 458 video and just realized how many videos I’ve missed,have a lot of catching up to do! This is a great video, appreciate all the effort put in for this
Thank you my friend. Ended up keeping the catted, headers and valves rear. Car is now an animal
Great video mate
Just stumbled upon your channel and this epic video, how has this not got hundreds of thousands of views is beyond me 👍🏻🙌🏻🙌🏻 great job brother, from 🇬🇧
Thank you my friend. Happy you enjoyed it
Well done, Mick! 🤙🏽
Thank you my friend
Just amazing
Thing sounds amazing 👌🏻🙌🏻
Thank you my bro. As quiet as stock when valves closed, and as loud as my 3RS when valves open. Just insane.
Soul has got both the GT4 and GT4RS game won with their valved rear boxes and street and competition headers. They truly make these cars sound perfect and the way they should have sounded from the factory. It’s amazing how they can limit the overbearing aspect of drone that so many other manufacturers can’t seem to get a handle on. Only other back boxes that sound nearly as good are from JCR imo, and while they sound great and look beautiful, Soul still has them beat in terms of value.
Couldn't agree more... Soul is killing the game with their setups. I'm in love with mine.
I had been waiting months for someone to make a detailed review of 4RS Soul products, the technical and sound comparisons were super helpful.
Get a promo code with Soul, I wouldn’t have pulled the trigger without your help.
They helped plenty with the exhaust. I’m happy you enjoyed the video 😎
Love this video. Porsche makes such a great product but their weakest point is the exhaust. Pretty amazing what you can do and all the configs available. And someone better snatch up that touring now!
These guys kill the exhaust game. The 4RS is now equally awesome to the DeMan.
Amazing 🫡
Amazing video man ! İ'll be getting in 2 weeks Akrapovic competiton headers , catted OAP and for rear section JCR valved exhaust . Can't wait though :)
Will sound sick.
Sounds great! Archie Hamilton just posted a video with a 4RS with a JCR straight pipe that sounds pretty nasty as well.
I watched it. I think the magic of the Soul Performance is that they made the valved exhaust with some canisters that eliminate drone. I’m in love with this setup. Will make a dedicated review of it because it sounds too damn good.
Thx! Super interesting video. Problem for me is maintaining warranty. Don’t want to loose that on a +300k car. A just back box can be a solution, but I want those headers singing that 996GT3 song.
You won’t void the warranty with headers. Porsche is not McLaren or Ferrari. I would do my setup… headers, valved rear, and catted OAP’s. This setup made me keep my car because of the cars duality. It’s barely louder than stock with valved shut, and becomes a crazy machine valved open.
Fantastic job man. Also, thanks for transparency and sharing the folder on the tunes. I too have been waiting to pull the trigger on the exhaust set up on my 4RS. Did they mention if the resonated OAP would be similar to OAP + Cat in terms of performance/sound? At what point do you think tunes will be coming up?
Performance is the same for resonated and the competition OAP’s. Sound is going to better on resonated than OAP + CAT and competition per John. He’s sending me a set. Will let you know. That being said I’m in love with how it sounds currently and no CEL
*sharing folder on the plots@@MiamiMiles What did you think of comparison between fab speed and the soul OAP?
Great video! the configuration that you liked best, was the Competition Headers, cat over axel pipes (not the competition over pipes), and the valve muffler, right? thank you for your clarification..
Yes. Correct
great video thank you. As a GT4RS owner, I love the intake noise inside and I don't want to amplify or change the noise inside the cabin. In your opinion, Which configuration will achieve that?? catted OAP's only?
I have the soul resonated OAP. It is very close to stock sounding. Only louder once valve open on higher rpm range. Induction noise unaffected.
Competition over axle pipes because the stock headers have cats. It doesn’t modify anything inside the car. It just amplifies outside of the car. That being said, my setup increases tone in cabin but doesn’t change the induction sound. It amplifies I interrupt sound. The car is 2x as awesome as it was. I have competition headers, catted OAP’s, and valved rear section.
i don't know why soul didn't design the rear exhaust the way so we can use those expensive tips. JCR has the tips i think. @@MiamiMiles
@@arta9769 because they tried and lost power. JCR had to make the exits of the exhaust smaller to fit those tips. That losses power. Soul does not like to lose power, which is why they did not retain the stock tips.
as one looking for strictly performance gains on the track, we don't spend much time in the 2000 to 4000 rpm range (idling in the grid?). A little disappointing that there aren't more gains higher up the rev range (5000 to 9000 rpm)
I think its a product of the car, not the exhaust. I tried Dundon on the car as well and the result was worse.
Great video! Exhausts make the car, period--don't care what care, if it doesn't sound right, it is no performance car. Put an AWE Track on my M4 Competition, and although I had wired the flaps fully open 2 years ago when I got the car, stock exhaust sucked, BIG improvement! Also had either Bullets or pulled the NPP fuse on my Corvettes. Flaps are moronic. You buy a performance car to sound like one. Not a UPS truck. Anyway, fun test!
Happy you enjoyed it my friend. Moving forward, I will have a valve controller on every car. Stupid valve operation makes the car sound like shit. Also, the M4 with an exhaust probably sounds 🔥 Thanks for the comment my friend!
Sorry if I missed it, but for the "stock exhaust" baseline...was that w/the valves open or closed? If it was w/valves closed, be curious to see the delta w/the valves open...because the factory back box is basically straight through w/the valves open.
Valves were open my friend. At least PSE was enabled
Lets see some 60-130s. Uncle pete is playing
How does this setup compare to Dundon mini-crack sound wise?
Dundon sounds sick but it makes no power over just over axle pipes from any company.
Picking up my 4 RS this Friday. Thanks for this video. I'm still confused though. What is your "near" perfect setup? I should just probably drop it off at Soul for them to install. I'm not far from them and have their product on my GT3 Touring. Big fan of their products.
Valved exhaust, competition headers and catted over axle pipes. It’s barely louder than stock with valves closed, and sounds like a cup car at 9k. Probably the best exhaust system I’ve ever owned
Agreed..have the same one on my 4RS. Super happy!@@MiamiMiles
@@jmartprjmartpr9944 I can’t believe how good this car is with this setup. For me it made the difference of not selling it.
@MiamiMiles The package is now complete. I also added a valve controller to mine but mostly just leave PSE off....it even sounds good valves closed.
@@jmartprjmartpr9944 I need the valve controller as well. Will purchase it asap based on your feedback
22:25
Will you take it to deman to get the 4.5L treatment????
Nope. Haha. I’ll keep my GT3 for that
John Gaydos is king 🤴🏼
Yes he is
