Meet the Soul Performance Products Competition Suite for 987.1 Cayman / Boxster - performance components built by enthusiasts, for enthusiasts.





DEVELOPMENT: We have had ample time around many exhaust configurations for the 987.1 and set out to build the ideal setup for enthusiasts. We decided on this design as it offers an incredible sound when you have the pedal down, but it is VERY refined when driving around town. The Soul mufflers practically eliminate droning – even with aftermarket catless headers the sound is reserved during partial throttle! No valves necessary – we are confident that our system is a solid option for those who like it loud when it’s appropriate but reserved around town. Expect no check engine lights





CONSTRUCTION: Each system is made from mandrel bent T304L stainless steel tubing and features mufflers with fortified casings in the interest of durability. Choose from three attractive 3.5” tip options - or we can even build you a custom set to meet your needs.



Our precision engineered headers are meticulously fabricated from T304L stainless steel. Proven design elements including port matched flanges, smooth radius primary tubing, and collectors that optimize the exhaust flow all work in conjunction to maximize power gains. Every set is rigorously quality-checked prior to shipping.

POWER: The 2006 Cayman S was advertised as making 276 crank horsepower from the factory, which translates to around / under 250 wheel horsepower. During testing on a Dynojet dynamometer at Eurocharged Cincinnati, a Competition Package equipped vehicle put down an average of 286 wheel hp and 244 ft-lbs of torque, with the strongest run being 291 whp and 250 ft-lbs of torque.






BOLT ON AND GO: Each product is tested in a fixture to ensure perfect fitment. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.




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 that you may have.

Soul,
Could/would you build a 200 cell cat model of your headers for 987.1 S cars. Specifically, I would like to see a 24 inch long tube header attached to a 200 cell cat, that I could connect to an aftermarket catless muffler, in my case a Milltec product. I have only found competition headers in your listing for my car model while 987.2 has a cat header.

I would think that 987.1 has 5 times as many cars on the road as 987.2 and rates this build. There are numerous enthusiastic 987.1 owners who do not necessarily track their cars, but use them on the street as either a daily driver or for sport. This type of header would give them little more mid range HP and torque.

I know there are exemption forms that I could use to get around the state DEQ requirement if I installed your headers without cats, but that process is very involved in the state of Washington.

This type of header would give a little more mid range torque, which is needed for autocross and also pass the Washington state DEQ.
Apex1 I'm sorry we missed your comment. I don't have an ETA on the headers you are asking for but they are on our development project list.

Thanks, I would think you could sell quite a few of these long tube headers, especially if they are longer than the competitions and look great in the under car shot. Maybe 20 inches would be more realistic for headers, knowing they flow into the cat. Do you also offer different coatings, as some are gold and others sort of silver?

Please let me know if you intend to pursue manufacturing this product or do you need a test vehicle. I would volunteer my car through a local speed shop if that would help for a 987.1 3.4 motor. Not sure about doing before and after dyno tests though. Its a pain to get my car to Cantrell Motor Sports in Bellevue. Maybe I could do a Cobb tune at the same time to add crackle into the down shift cycle and add some mid range torque.

We have to manage pricing vs performance for the 987.1 We're exploring our options for runners and catalytic converters and will getting into development in the distant future. We do not offer coatings - we leave that up to the customer to decide what they think is best - it's best to go direct there. We have a local vehicle that we can use for development when the time comes. Unfortunately COBB does not support the 987.1 models.

I feel like I need to provide another update.


I have the full exhaust (long tube headers + mufflers) and as reported in other threads, my car came Alive after this upgrade. I have stock intake, TB and even OEM Air filter and yet the car was transformed after this upgrade.
A big jump in low end TQ, mid range. I never had PSM interfere on exits of corners until I added the exhaust. I didn't need to take the car for a dyne run to feel the change in HP.

A week ago I added a Tune to the car, The tune company's claim of HP/TQ addition are similar to what Soul Performance claims I got with headers/mufflers. Well, life is full of lessons learned because those claimed ponies never showed up. I am sure the car is technically making more HP/TQ than it was before tune. But there change is absolutely not nearly as much as I got from the Exhaust system (especially Headers)

Do you recommend Titanium heat tape wrap to increase internal temp and reduce outside temperature on your competition headers all the way to the rear muffler, especailly around 997 turbo brake cooling ducts installed on 987 on the thrust arm to cool the rear brakes. Also, is it possible to install the competition headers and then add a 100 cell cat just before the muffler with the Titanium tape all the way to the cat. Is there a reason the cat needs to be closer to the motor if the pipe is wrapped?

I plan on having two different brake cooling ducts in the rear, the 997 Turbo on the rear thrust arm and a GT2 duct banded to the lower control arm. One is in front of the brake and the other is in the rear of the brake. The reason is the that 987.1 do not have a PSM defeat to turn off the rear brake stability during trail braking, so they work a lot harder than they should and get very hot.

Ceramic coating / heat wrap is like you said a great way to keep heat in, which in turn increases exhaust velocity while prolonging the life of components near the exhaust. The further back you place a catalytic converter from the engine the less efficient the catalytic converters will be for emissions purposes - you want the cats hot and at optimal operating temperature for effective catalyzing to take place. Given you are adding cooling components and discussing trailing braking will your car be primarily seeing track use? Any reasons for the cats as you could disable any CEL's with a tune?
