Soul Performance, Sport X-Pipe Exhaust System with Sport Catalytic Converters, Porsche 991 Turbo & Turbo S, (991.1 - 991.2, 2014-2020)

Porsche 991 Turbo Sport X-Pipe Exhaust System Full catted exhaust delivers a sophisticated increase in sound with no check engine lights. Proprietary X-Pipe design, 3" piping, and quad race resonators encourage maximum power gains and an exhilarating increase in flat six engine note and turbo wail. DEVELOPMENT AND TESTING: We wanted to build an aggressive catted system that offers a modest increase in tone - including pops and burbles on deceleration - without triggering a check engine light. Support for high power was another consideration - necessitating 3" tubing. We experimented with adding a mixing chamber into our X-Pipe design. Analysis in 3D CAD software showed a general increase in velocity gained downstream of the mixing chamber across a band of measured pressure and temperature levels. This produces optimal flow characteristics, reduced backpressure for higher HP, and enhances the sound quality of the system. Quad race resonators make a discernible difference in reducing dro
