Replace the restrictive factory catalytic converter with a bolt on, high flow HJS HD 200 cell catalytic converter downpipe for more power, response, and turbo sound without a check engine light or noxious fumes.
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 HJS HD 200 cell catalytic converter and smooth mandrel bent piping ranging from 90mm down to dual 55mm oulets encourages better throttle response and a more exciting exhaust note. Easy to bolt in with no modifications required, this is a great, reversible solution to make your Boxster or Cayman more exciting.
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.
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. The 200 cell design uses a premium wash coat of precious metals to achieve a high level of effectiveness at catalyzing even with the increase in exhaust flow.
BOLT ON AND GO: Each downpipe is tested in a fixture to ensure perfect fitment and then foam packed to ensure they arrive 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.
