DEVELOPMENT AND TESTING: The 718 is rather quiet in factory format. Replacing the restrictive factory catalytic converter with a freer flowing unit adds to drivability and also unlocks the sweet sounds of the turbo without adding any negative notes to the overall exhaust tone. The high-flow catalytic converter and smooth mandrel bent piping ranging from 90mm down to dual 55mm oulets encourages better throttle response and a more exhilarating exhaust note. Easy to bolt in with no modifications required, this is a great, reversible solution to make your Boxster or Cayman more exciting.
POWER: Verified independent dyno testing at Growler Motor Labs revealed real, repeatable peak gains of 14 whp and 24 ft-lbs of torque with a noticeable improvement in the mid RPM range.
CONSTRUCTION: Each downpipe is assembled out of mandrel bent, thick wall T304L stainless steel, then rigorously quality checked. Back purged TIG welding ensures proper weld penetration and longevity.
BOLT ON AND GO: Each downpipe is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition.. New hardware is included for the two bolt flanges. 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 for life! Our team will quickly work with you to resolve any issues or answer any questions that you may have.
