DEVELOPMENT AND TESTING: By creating a unique application for the 987.2 platform, we’ve focused on sizing the runners (2”) and collectors correctly to extract maximum power from the 3.4L engine while producing great gains from the 2.9L as well. During dyno testing on a Dynojet, we experienced max gains of 8 whp and 11 ft-lbs of torque at 4,100 RPM on the SOUL project Cayman S with PDK. Even greater gains can be expected when paired with a tune as seen on the dyno chart below with massive gains.
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. Choose from a variety of 321 stainless exhaust tips in different styles and finishes – or contact us to customize your own set!
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!
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 header set is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure they arrive in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
