SOUL | 997.1 Turbo Exhaust Suite
We're proud to announce availability of our 997.1 Turbo exhaust suite http://soulpp.com/wp-content/uploads...rum-Banner.jpg Competition X-Pipe Exhaust System Sport X-Pipe Exhaust System GT2 Style Bolt On Exhaust Tips http://soulpp.com/wp-content/uploads...lery-Forum.jpg DEVELOPMENT AND TESTING: We wanted to get as aggressive as possible while minimizing drone – greater volume with a greater amount of pops and burbles on deceleration. Support for high power was another consideration – necessitating 3″ tubing. We experimented with adding a mixing chamber into our X-pipe design. Analysis in 3D CAD software showed a general increase in velocity gained downstream of the mixing chamber across a band of measured pressure and temperature levels. This produces optimal flow characteristics, reduced backpressure for higher HP, and enhances the sound quality of the system.The 997 Turbo is very prone to drone when you start to uncork it. For our Sport variant, HJS HD 200 cell catalysts do a great job at keeping the sound level and quality at a reserved and refined tone - definitely daily driveable. Once we removed the cats for a Competition version, drone was present in the 2,000 - 3,000 RPM range by a fair amount. We tested out different resonator types, amounts (0, 2, and 4) and found best results with 4 resonators. We even tried to use rubber isolators to reduce drone but the effect was not noticeable. https://soulpp.com/wp-content/upload...-Flow-Data.jpg https://soulpp.com/wp-content/upload...evelopment.jpg We pushed on and added helmholtz resonators using calculations to specifically target droning further in the lower RPM's where it is most pronounced. They proved to be quite effective - greatly cutting down on drone as intended. The final result is a car that has a great tone with an acceptable level of in cabin presence - drone is still present at low RPM to a degree but this IS a catless race exhaust. CONSTRUCTION: Each exhaust is made from mandrel bent T304L 3″ .065″ wall stainless steel tubing, straight through race resonators with a full metal packing design for maximum durability, and laser cut brackets for perfect fitment. Choose from several hand finished tip options to get the look that suits your 991 the best – or reuse your factory tips. Mikalor Supra Heavy-Duty Clamps are included to securely hold our tips onto the system. HJS CATALYSTS: The highest quality catalytic converters available, known for their industry leading flow and durability. They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow – all without a check engine light. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse. We use a large and appropriately sized catalyst to allow for maximum gains – no compromises here! POWER: SOUL is seeking a 997.1 owner to participate in third party dyno testing with all costs covered by us to provide full power numbers on all configurations - please contact is if you are interested. WEIGHTS: The Competition exhaustweighs approximately 16.2 lbs / 7.3 kg less than factory exhaust components (28.8 lbs vs 45 lbs) while the Sport exhaust weighs approximately 10.8 lbs / 4.9 kg less than factory exhaust components (34.2 lbs vs 45 lbs). CHECK ENGINE LIGHT?: Expect no CEL with our catted Sport X-Pipe Exhaust System. Catless, most likely, but chances can be reduced with our catted O2 spacers. 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. https://soulpp.com/wp-content/upload...-Wall-Tips.jpg IN STOCK AND READY TO SHIP!

Very nice touch on the resonator. I had a competitors X-pipe exhaust with with 200 cell cats and got rid of it because of the drone. Annoying as hell. Great work! Good luck with sales. |

Love the GT2 style tips...I have been looking for them...unfortunately I may be putting your tips on my new Europipe stage 2 exhaust system I just ordered, I really think their sound is a step above anything I have heard not to mention with only .12 bar back pressure (with 6 inch 100 cell cats) they flow quite well. I wish you nothing but the best with sales though.

The GT2 tips from Soul Performance fit my 997.2 Europipe perfectly. I would expect the same fitment for your 997.1 Europipe...but, I should let the experts chime in....

SOUL Staff,
Is it possible to achieve stock/OEM/refined like quietness during light throttle cruise operation, similar to Kline Innovation's smaller diameter exhaust system while retaining really pronounced turbo spool sound like Europipe has? Kline is attractive as it sounds refined but not very Turbo-ish where Europipe is too boomy for me however spool sound is intoxicating. I understand that I might be asking for a lot here. Many Thanks, Dmitriy |
Dmitriy, thank you for asking, I'll do my best to answer your question. You're asking for both quietness and selective loudness from a non-valved system which is a challenge. Our main focus was on reducing drone as much as possible while still offering an authoritative exhaust note. It's very easy to uncork this platform and introduce drone, I'd say that mitigating it is the overall goal for the 996 / 997.1 Turbos. We're using 3" tubing through most of the system which will lend to a more aggressive and deeper sound. Our x-pipe design and quad resonators prevent a booming exhaust note inside the cabin but there is certainly a good presence to let you know you're driving a high performance machine. The Competition system incorporates anti-drone tubes to compensate for the lack of sound attenuation that the cats offer - specifically in the 2,0000-3,000 rpm range. You will not experience an OEM like quietness off throttle even with these provisions as we chose larger piping and introducing an aggressive note without it being too aggressive. One can expect great sounds from the turbos (which we felt was mandatory) with a good tone - while not as high-pitched as smaller diameter systems - but intoxicating none the less. We didn't want to error on the side of offering an exhaust that would be too quiet or "boring", one that would not support decent power levels, or be so loud as to be only for hardcore enthusiasts.
We invite anyone considering our systems to call us for a chat that can be as quick or as in-depth as you want to make sure we can meet your needs and expectations. You're spending a lot of money to enhance a prized possession and you should get what you want, and even if it's not a SOUL component we'll point you in the right direction. We're a customer service company that also builds exhausts, take advantage of us!

"Once we removed the cats for a Competition version, drone was present in the 2,000 - 3,000 RPM range by a fair amount. We tested out different resonator types, amounts (0, 2, and 4) and found best results with 4 resonators. We even tried to use rubber isolators to reduce drone but the effect was not noticeable." Sorry but we don't share how we achieve our results as it gives away a competitive advantage. The calculations are rough and manual testing is needed as a lot can change depending on where the drone tubes originate on the system and different variations further upstream influence the effect as well. We tend to not record the results as it's hard to detect drone in a quantifiable amount unless we got surgical with the recording process (constant gain mic, same exact road and weather conditions). https://soulpp.com/wp-content/upload...etubenotes.jpg Here is an example of notes from the extended development of our 991.2 Carrera base non-PSE rear exhaust. This is John Gaydos' personal notes of where and how much "drone" was experienced in the cabin through various setups during test driving. We took the opportunity to experiment with different locations of the origin of piping along with different lengths. As you can see the results can vary widely depending on these factors. When you see anti-drone tubes on our systems - know we put extensive testing into ensuring they are effective. As it pertains to the quality of sound, anti-drone tubes are great at removing drone while retaining volume and "sharpness". Resonators cut down on negative qualities such as rasp and overall reduce sound volume, we use them more for rasp and drone control than overall volume control where a muffler would be ideal. On the 997.1 these drone tubes are an extra effort to isolate a specific area where mufflers and resonators would need to be much larger or abundant to control these factors while neutering the sound. -Mike |
Thanks for the response. I was referring to your helmholtz resonators (what you are calling anti drone tubes). The 4 'resonators' you are using are more like mufflers IMO (straight through 'absorbing' type mufflers).
The drone on these cars is around 2500-3000 like you say. Simple apps on your phone can easily isolate that frequency. From there you can calculate the length of the helmholtz resonators to reduce that frequency. Things like position, diameter, and other things (mufflers) in the system can change how they work. Sounds is pretty handwavy so I agree testing is the way to go. The reason I asked is because if you do the calcs for 129hz the helmholtz resonator should be significantly longer than what you've designed. Don't get me wrong, your exhaust sounds very good and looks amazing, I would buy it :). It was more of an engineering question in regards to the approach. https://cimg4.ibsrv.net/gimg/rennlis...0e43a72f8d.jpg |
The helmholtz resonators could likely be more effective if longer but we are limited by packaging restraints under the vehicle and the quad resonators already have a good effect, they are implemented to take the edge off the increase in frequencies from removing the catalytic converters. They're quite effective given their size though. We've tested with a gamut of programs, calculations, recordings and nothing beats practical experimentation!
-Mike |
I agree, sound is so qualitative for an exhaust, physical testing is a totally reasonable approach.
|
Dear Soul performance.I have enjoyed my Competition X pipe Exhaust on my 2009 6MT TT, but I’m curious as to why it doesn’t crackle and pop during deceleration like it did when it was first installed, and it’s aggressive sound has definitely diminished. What could possibly be affecting it. Your thoughts?
Thanks, |

We use 1/4 wave resonators and they are absolute magic. We use them on 3.5" Titanium straight pipes which prior to the resonators had absolutely unbearable resonance even with ear plugs. With the resonators, the sound is totally changed, slightly deeper and with virtually zero drop present. You can easily skip earplugs now which is amazing considering there is no muffling present. At idle the sound is downright docile. This is on a 4.0 turbo Mezger. For optimal performance, you want the resonators to be as straight as possible and resonator length and tubing diameter have to be taken into account along with the rpm at which the offending resonance is occurring which in our case was 2600-3100. There are formulas which assist in calculating the resonator dimensions. When done properly, 1/4 length wave resonators are amazingly effective. I have used 1/4 wave resonators on my previous three X-pipe exhausts and the results were the same. I would not run an exhaust without employing these on this platform.
Note the discoloration of the Ti pipes after a season of heavy track use. Your straight pipe setup is basically what I was envisioning to built and test on my car. Glad to see someone else do it that way and confirm the drone is all but eliminated. |
Hello, I have FVD exhaust (Brombacher) on my 997.1 turbo and it has huge drone around 2300-2900 rpm which is annoying - my car is DD.
Is this exhaust really without drone? Can I reuse cats which were supplied with FVD exhaust? - https://www.fvd.net/us-en/BES9971524...port-cats.html Do you have dealer in Europe which has exhaust in stock? |

Here's an awesome video by our dealer Flat 6 Motorsports featuring our Competition X-Pipe Exhaust System:
-Mike |
How adjustable are these? I'm unsure if one of my aftermarket tips was positioned poorly or if it's another issue (due upgraded exhaust by the previous owner). The color of my 997.1 Turbo is atlas grey metallic and I'm interested in the brush finish.
Apologies as I was referring to the GT2 tips. |
This is the result you can expect from our 996 / 997.1 Competition Exhaust System from passengers: :D
-Mike |
We've updated our Turbo systems to incorporate a new CAD designed cast X pipe which yields less welds and a smoother internal transition for maximum flow. We're dedicated to improving our components whenever we can and we appreciate your orders and interest through the years!
https://i4q6a2d6.stackpathcdn.com/wp...ipe.jpg?x11192 -Mike |
Purely out of interest how do you determine that the change is a positive one?
I understand that the exhaust gases are quite lazy, so is it the width of the X-pipe section that improved the flow? So same velocity is remained and restriction is reduced, or? Edit: Derp, you did say smoother welds so that's probably it. Edit #2: Funny, the video above said Sport OFF vs Sport ON. At first I thought it was a valved exhaust until I had realized you were talking about the Sport Chrono. When I datalog I had noticed that at idle we go from (6 degrees I think? to -6 degrees of timing), I also think the Turbo Vanes change position, both yield the sound change. Maybe RPM is bumped up too? Overall, all I am saying is it was interesting to observer and then to remember the data and to see it in your video. |
Utilizing the cast design versus hand making the X-sections allowed us to make a more ideal interior design in terms of flow - smoother internal surface (no welds like you mentioned) and a smoother ramp up into the X-chamber. Casting this section allowed us to design it with no physical restrictions like making it it from piping did. We did CAD simulation testing with both setups and the cast design was optimized until it had slightly improved velocity out of the X versus the old design. The new cast X adds around a pound in weight but the increased density should absorb some of the negative frequencies inherent to the platform better.

Does this fit the 997 GT2?

Isn’t the 997 GT2 a 997.1 motor so the .1 exhaust with different tips would fit? No?
