Porsche 718 Boxster / Cayman Competition Downpipe

DEVELOPMENT AND TESTING: The 718 is rather quiet in factory format. Eliminating the restrictive factory catalytic converter adds to drivability and also unlocks the sweet sounds of the turbo with a major increase in snarling and crackles from the exhaust. The sound is aggressive without droning in the cabin. Smooth mandrel bent piping ranging from 90mm down to dual 55mm outlets 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. We highly recommend an ECU tune with this modification to prevent boost spikes that result from the major increase in exhaust flow. CONSTRUCTION: Each downpipe is assembled out of mandrel bent, thick wall T304L stainless steel, then rigorously quality checked. BOLT ON AND GO: Every 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. CHECK ENGINE LIGHT?: This product may trigger a check engine light due to removal of the factory catalytic converter. (for track use only).
