2018 Porsche 718 Boxster Base Performance Parts

DEVELOPMENT The factory rear muffler wasn’t much of a restriction on the standard 718 GT4, but reusing it for the GT4 RS has created a bottleneck for the GT3-derived engine. The tubing diameter remains the same, meaning that increased power is now forced through...

DEVELOPMENT GOALS Improve upon the factory design and achieve a throatier / smoother / higher pitched tone. The original tubing diameter—less than 2¼ inches— restricts power output. Although this design helps meet sound regulations and simplifies manufacturing, it doesn’t maximize the performance capabilities of...

For the standard 718 GT4, we offered both a catted and catless solution for a header replacement. But in order to follow suit with the GT4 RS that would introduce necessary compromises–so we didn’t do it. For a transformative solution that still retains catalytic...

DEVELOPMENT:  The factory Boxster / Cayman “T” tip section allows for exhaust gasses to crash into each other when coming out of the muffler before exiting the tips. This cost cutting method creates turbulence and hurts performance. By incorporating a smooth, cast X-pipe into...

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....

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...

DEVELOPMENT:  Our goal was to offer a valved exhaust that delivers a refined cabin presence. It is easy to increase the volume of the 718, but a challenge to bring out a more aggressive note while making the flat four sound distinctly Porsche which...

DEVELOPMENT:  Our goal was to offer a valved exhaust package that delivers a unique and aggressive exhaust note without sacrificing a refined cabin experience – from mild to wild at the press of a button. An upgraded downpipe greatly enhances the character of the...

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...

CHECK ENGINE LIGHT?:  The catless section may trigger a check engine light due to removal of the factory catalytic converter. We suggest a custom ECU tune to disable any check engine lights (for track use only). LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence...

DEVELOPMENT GOALS Improve upon the factory design and achieve a throatier / smoother / higher pitched tone. Increase the presence and character of the exhaust note in the cabin while maintaining a reasonable level of resonance / drone while driving in both the valves...

DEVELOPMENT: Would it be a GT4 exhaust suite without upgrades for the track enthusiasts? We redesigned the entire exhaust aft of the headers for maximum flow. The factory dual exit/entry flanges connecting the over axle pipes to the PSE muffler limits the piping diameter...
