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. 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. You can order the exhaust to suit your specific aesthetic desires select from our Signature Satin or a full polish finishes, with tips of your choosing. <br><br>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!<br><br>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. <br>
