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 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.

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.

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. We cover our HJS catalytic converters with an unprecedented 3 year warranty while the materials and workmanship are backed by our Lifetime Warranty.

    The sound while driving the car is greatly increased. It sounds like the PSE, but noticeably louder and without any drone. Which is exactly what I was hoping for.

    The turbo is barely noticeable – just enough to hear it without it being too much.

    Most importantly, my butt dyno is telling me that the downpipe added some power. The car feels to pull through the gears much easier. Enough so for me to actually notice a difference.

    Overall, I think this was worth the money and made the car more fun to drive – without costing an arm and a leg.

    Lovely turbo spool sounds coupled with great (louder & deeper) low end grunt and a bit more power according to the unofficial butt dyno. I’ll hopefully be attempting some more video from the outside soon. Fit and finish of the downpipes is great, the o2 sensor installed with no problems.

    Removal of the stock setup required some wrestling of clamps and stubborn screws, but everything was installed and buttoned up within 2.5 hours which included getting the rear up on jack stands and removal of the rear wheels.

    I’m definitely looking forward to driving more with the downpipe as well as hopefully getting to Cobb so they can play around with the new found flow and power.
