DEVELOPMENT AND TESTING: We wanted to get as aggressive as possible while minimizing drone – greater volume with a greater amount of pops and burbles on deceleration. 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 drone while encouraging a more refined exhaust note.
Let the true character of the 991 Turbo be heard with an aggressive yet refined sound to match it’s performance. 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.
