Hello,

My name is John Gaydos, SOUL's newest addition as their Performance Specialist. You may recognize my name from several past roles in the aftermarket performance industry, and I am now here now to take care of any of your needs. To say I’m excited to join the team and grow the company is an understatement. During my time here I aim to bring the Soul brand and product line to greater national/international recognition. I will be expanding our product line and partnering with “A Players” in the industry to become the one-stop shop for everything you need to maximize your driving experience. In doing so, I will not lose site of our core values and will maintain a hands-on approach to our community and customer involvement. Expect to see me at shows and various tracks as I will be traveling to network and meet more good people/shops to work with. I will also be participating myself with my Cayman R. I’m aiming to instruct with PCA in the 2019 season both at track days and AutoX, and I plan on participating in some endurance racing series as well. We are going to have a lot of fun, and I invite you to join us! If you are in the Tristate Area, I'd love to meet up with some of the locals at upcoming events. Let me know what you are up to and when : )

Don't hesitate to reach out with any inquiries you have on enhancing your various vehicles, I would love to catch up and chat about your project. Feel free to email me at [email protected], or call/text me at 484 883 6197.

Back on the thread topic...I have always preached that the biggest return on investment on the Boxster/Cayman platform is upgrading the headers. Not only is the sound improved, but it is the lowest hanging fruit on taking the performance up a considerable notch. And we have them in stock! As always an educated decision is the best decision, so give me a shout to chat about it if you're interested!

Pulled the trigger a few weeks back and received, what I am told, the first commercial set of Soul Performance catted headers for my 987.1 CS. As all the others have shown at unboxing, they are a very nice piece of engineering and execution; a very pretty piece of equipment and a shame to hide under the car.

Install is as described elsewhere and not a very challenging upgrade. It took me about 4 hours on the lift, start to finish with about 3 hours of actual work taking my time and figuring out the angles to attack some of the bolts. After 102k miles, the header bolts came out with little resistance. I did soak with an acetone/ATF mixture for about 10 minutes. That stuff eats right through anything. Space to get at the 3 bolts on the exhaust flange to the cat back are a royal pain. Lot's of extensions, universal joint combos to get at the ones inside. Probably would have been easier to loosen the rest of the muffler. Also installed new O2 sensors. Likely overkill but had been throwing codes for months.

Fitment is exact with what appears to be a very robust manifold flange and great, clean welds. Not to mention the matte finish. Again, should be seen AND heard.

The pictures below show the exhaust and hopefully the videos come through. Before video is stock headers and Carnewal GT exhaust. Next video is the Soul Performance catted header and Carnewal GT Exhaust. The sound difference is much more distinct in person. Car sounded pretty nice with stock header and Carnewal. The SP header deepened the sound immensely. It is a very refined note that builds to a crescendo that rips the end of the exhaust tips. It is an amazing sound.

I run an OFT flash that seems to work well at freeing up the power and runs much, much better than stock. So far, the SP header seems a bit more free breathing using the power even a bit better. The car is very happy and winds to 7k quickly with little lag. Only butt dyno so no numbers to go with anything but a bigger grin.

Many, many thanks to John at Soul Performance. He pushed me over the edge to get them. It has taken me a couple of weeks to install as my travel schedule has been heavy. It hurt to walk past them sitting in the garage. Very thankful John got me into them. Great communication throughout the build and delivery.

BTW, I know the car is dirty. She is no garage queen!!!

Rlazer3- I have boiled my header search with cats down to two, Soul and Cargraphics. Both were designed with as long a tube header that fits the 987.1 Cayman. My needs come from autocross where mid RPM torque is king. I also want these to work on the street and pass my State's DEQ requirement of a probe up the exhaust pipe while idling.

My question is did you look at Cargraphics before buying from Soul? They are a few hundred dollors more and made in Germany through Flat6 Motorsports. There is no dyno comparisons, but the pipe of the Cargraphic set is 1 3/4 in vs 2 inch on the Soul. Does that make any difference. I think the Cargraphic pipes are a couple of inches longer before the collector/cat.

Apex, this may be best answered by John at Soul Performance or Jon at Flat 6; both generous gentlemen with their information and attention! I am no engineer so I cannot attest to pipe sizes or length. You may be headed toward splitting hairs with one against the others for perfance.

I do care about emissions but living in Florida we do not have testing. Again, the experts will be beater suited to answer.

I went with Soul after many months of watching them introduce into the P world and considering all options for years. After several weeks of driving with the Soul Headers I can tell you the amount of usable power throughout the rev range is much, much better than stock. Mid range is big winding to 6500+ rpm freely and without noticeable flat spots. Real bonus is the drone is all but gone between 2300 and 3000 rpm. Almost completely gone.

The combination of the IPD Plenum, GT3 TB, full exhaust, and flash is massive difference over stock. I stepped through the upgrades one at a time so I saw stepped improvement. Each upgrade was noticeable. Altogether they are smile inducing. I am very happy with my decision with Soul Performance. Cannot see that more $$ will buy any more noticeable power. I would use the difference for another weekend DE and be happy to hear the scream on the track; intoxicating.

Good luck with your decision and be prepared to hear the car as it should be heard.

Thank you for considering us. Our long tube runners and their larger diameter will encourage midrange to high end power gains. The tubing volume was chosen to to give better usability in the 3k RPM range to 5k, we chose increasing max power gains over a peak power gain as how often will you really be chasing the rev limiter vs spending time all over the RPM range.

Our 987.1 Long Tube Street Headers are now available!



DEVELOPMENT & SOUND: The factory header design is a very simple, mass produced component not suited for performance. By creating a unique application for the 987.1 platform, we’ve focused on sizing the runners (1.75”) correctly and incorporated high quality spike into the collectors to extract maximum power from the 3.4L engine while producing great gains from the 2.7L as well.




CONSTRUCTION: Each 987.1 header set is assembled out of T304L stainless steel and rigorously quality checked in-house. Merge spikes are incorporated to smooth exhaust flow into the collector and increase power. Thick water jet cut flanges cut to ISO 9001:2015 standards ensure perfect fitment and product longevity.




HJS CATALYSTS: We use the highest quality catalytic converters available, known for their industry–leading flow and durability. They are efficient enough to meet strict EURO 3 emission standards while still allowing for an increase in flow while greatly reducing the chance of getting a check engine light. The HJS HF design uses premium double foil winding for exceptional strength and durability.





BOLT ON AND GO: Each set of catted headers is built and tested in a thick gauge aluminum fixture (which prevents warping) to ensure perfect fitment. New high grade hardware is included for the header to exhaust flange.

MSRP: $2,795

I'm currently enjoying the sound and performance of your 987.1 competition headers, and I highly recommend them, but they require a suitable "race" ECU software tune to both prevent a CEL and extract maximum performance. The combined price of these two mods is roughly the same as a pair of these street headers, but unfortunately these mods wouldn't pass inspection in most of the states that require emissions inspections.
These street headers appear to be very well designed and beautifully manufactured. I would strongly considered these as a "plug and play" alternative to my configuration.

Thank you for your input and kind words! Ultimately with catless headers and ECU tune you will end up with more power and volume for the same amount of money, but it's an all in situation and like you said - there are some cons. We always invite anyone to reach out to us to discuss their unique goals and consider a mod path and plan to get to a desirable result!

I have the Soul Performance catted headers with Carnewal exhaust. I run an OFT flash with 2 programs; one more agressive than the other. I have run stock, program 1, and program 2. The sound difference is sunbstantial from one to the other. Most agressive is a wonderful sound that can be modulated with the throttle. Go easy on the throttle and get a nice rumble that is not too loud or aggressive sounding. Give it some gas and it's the sound we are looking for. Program 1 is less loud and deep. Stock is still a great sound and would be considered ideal if you did not hear the other two programs.

As for performance, there is a difference between the flashes, as well. It is noticable between them. I would be shorting myself (in performance) with all the mods if I did not have the flash.

As I posted earlier, the build quality is outstanding and the fitment is spot on. Easy install and especially easy working with Soul.

Thank you for sharing, we're glad to have you in the family!

Riazer3- How did you get the two OFT flash programs to sync up to the Soul catted headers and IPD GT3 throttle body? OFT web site is not user friendly and I am trying to figure out which one will produce more HP with the Soul Long tube catless 2 inch headers along with the Milltec muffler/tips. On the induction side of my M97 is a GT3 throttle body and Agency power plenum with a Evoms filter. With FVD, I can simply write in the upgrades and someone in Germany will program the flash. I just want a line of sight for an outcome of 300 HP @ 6500 for my 3.4 M97 engine. I run 92 octane Chevron gas.

Any ideas on how to bring these modification together to produce a smooth power band with OFT flash/Soul catless headers/GT3 throttle body/Evoms etc, maybe using your duplicate flash through OFT? My use is for autocross, DE's and daily drives. I could do a dyno at the end of the install for actual HP results just to confirm the details.

Mike,

When I bought your catless long-tube headers you did not sell a street version. Is there a trade-in program?

Thx

We don't have a trade-in program but I will make sure that you are taken care of. Messaging you now!

Apex1,

I have been trying to get an optimized flash from OFT since before I installed the headers. I have always run rich with their flash and cannot get anyone to answer a phone. I finally got a rep to email me back with a canned response. I asked again to answer the phone so I could have a real conversation to get to a solution.
I am not happy with the OFT flash and am actually running stock right now.
No response from them so eff'em and onto a more reputable vendor or a custom tune. I am working through the possibility of bore scoring now so I am not pursuing anything now until I finish an analysis; that's another story...

So to answer your question, no I do not have a solution that gets the most out of our mods. I will pursue further when I have the engine sorted out. If bore scoring, I will likely replace with a 3.6 so I can keep the current mods and not start all over with a new car or engine block.

It's a shame with Shiv at OFT as I was impressed with his attention in the beginning. He appears to be more into BRZ, FRS territory and no longer interested in P cars. I cannot say I would recommend them to help you get the power out of the car.

Riazer3-I feel for you and your engine. LN and flat 6 innovations have a 4 part series on a youtube type video regarding bore scoring and other topics around the 987.1 M97. I am sure you have taken notes from Jake Ruby as he explains the results and the potential causes of bore scoring. The interesting note is that this is a changing landscape as the fuel mixtures (additives) are changing and most likely not known to us as users. From ethanol to the risk of pre ignition in the direct injection cars and/or turbo cars have all changed the additive packages. These additives do affect the protection material on the piston skirts to some extent.

Thank you for your response regarding OFT. Saves me a lot of time & mental energy.

Apex1,
I have watched all as they came out and have emailed back and forth with Jake. What started it all was, of course the amount of smoke and oil burn. I had the IMS upgraded and new rear main seal (upgraded) when a new clutch was installed last summer. Found some (a lot) of metal in the filter when I did last oil change. Will run 2000 miles on this change to then check oil filter again then bore scope the #6 cylinder, and likely #5 at that time to get some picture. I am burning a liter of oil about every 500 miles or so. Engine still runs what appears to be great.

Driving me crazy as I have new JRZ's and some other suspension upgrades to throw on. Waiting to decide what to do. I am pretty sure I will keep the car and do engine swap before selling and moving to DFI car or even 981 S. I just don't feel the extra money for a new(er) car will buy me any more happiness in the experience. For $15k or so I have the car I want instead of starting new and rebuilding.

Question on your FF orange insert...how has that effected performance? I have one and have not installed yet.
