DEVELOPMENT: The 718 has ample sound deadening and is further quieted down by the turbocharger making for a mellow cabin experience with both base exhaust and PSE. To some this will not stand, and for them we built an aggressive system designed for aggressive use. Suncoast Parts were looking for a durable system for their track vehicle which experienced a failure with another brand’s exhaust and as such we beefed up our Performance Exhaust to excel on the racetrack. Flex sections in the over axle piping and bespoke mounting brackets for both manual and PDK transmissions promote longevity and reduce NVH. 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. 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. The dual piping encourages a smoother, more refined rumble over a single piping conversion for a more distinctly Porsche engine note.
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 with just the downpipe alone!
CONSTRUCTION: Each system is made from mandrel bent T304L stainless steel tubing (featuring 2.5″ OD over axle pipes), thick cast flanges, and durable flex sections. 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.
SOUND: During development we were told this is the best sounding 718 exhaust several people have ever heard – and we concur! This exhaust setup offers an impressive level of snarling and crackling heard from some distance! This exhaust forgoes any mufflers and resonators and as such will have in-cabin presence which is sorely missing from the factory setup and with high flow cat downpipe will be on the loud side – be aware this is a very aggressive exhaust setup and will sound and perform as such – perfect for those looking for an invigorating experience but possibly too intrusive for the casual daily driver. If you are looking for an absolutely drone free experience with an aftermarket downpipe, consider our Valved Exhaust.
TIPS: Choose from several different tip styles and finishes. Single wall tips have around a half inch of depth adjustment to allow for the tips to be sunk in to just show the logo at their deepest and pulled out more if desired. Logo customization and custom tip colors are available by request.
BOLT ON AND GO: Each exhaust is rigorously quality-checked, tested in a fixture to ensure perfect fitment, then foam packed to ensure everything arrives in perfect condition. New hardware and gaskets are 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.
