SOUL Porsche 997.1 Turbo Sport X-Pipe Exhaust System

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 drone while encouraging a more refined exhaust note.

SATISFYING SOUND

The SOUL catalytic converters flow extremely well, letting through more turbo and flat-six sound through. Quad resonators add a refined tone and cut down on droning in the cabin. The level of volume is perfect the owner looking for a sophisticated increase in sound – aggressive on heavy throttle inputs while offering a mild and sporty presence during cruising.
