The Soul Performance Products Competition Package for your 987.1 Cayman / Boxster is built by enthusiasts, for enthusiasts. Look at the stock headers on your car, you can see the massive catalytic converters, thin flanges and squashed primary tubing – ultimately holding back power. Moving rearward to the OEM exhaust system, a secondary set of catalytic converters is in place within the exhaust to prevent power even more. The Soul Performance Products 987.1 Competition Package focuses on all of the weak points of the OEM exhaust system and replaces them in one fell swoop. Designed to work in perfect harmony, the Competition Headers and Performance Exhaust System rely on a mutually beneficial design. The headers use large, long primary tubes that flow into a smooth merge collector and the Performance Exhaust System uses mandrel bent over-axle pipes while deleting the secondary catalytic converters for a great increase in exhaust flow. Our fortified, high flow mufflers encourage a tasteful but hair raising sound while minimizing drone. You’ll greatly enjoy the increased responsiveness and character of your car!
PACKAGE INCLUDES:
Soul Performance Products 987.1 Performance Exhaust System
Soul Performance Products 987.1 Competition Headers
DETAILS
+ Fits all Porsche 987 Cayman / Boxster vehicles (2005-2008)
+ Direct bolt on installation – instructions included
+ All Soul Performance Products are backed by a renowned Lifetime Warranty for both street and track use
CONSTRUCTION: 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. Each system is made from mandrel bent T304L stainless steel tubing and features mufflers with fortified casings in the interest of durability.

POWER: The 2006 Cayman S was advertised as making 291 crank horsepower from the factory, which translates to around / under 265 wheel horsepower. During testing on a Dynojet dynamometer by a third party, the 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.
TIPS: Choose from several different tip styles and finishes – from single wall 321 stainless tips to double wall chrome tips. Logo customization and custom tip colors are available by request. Titanium single wall tips are also available and save nearly a pound of weight over stainless steel tips!

BOLT ON AND GO: Each exhaust is tested in a fixture to guarantee fitment and then foam packed to ensure it arrives in perfect condition. 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 or answer any questions that you may have.
