Porsche 996 GT2 SOUL Competition X-Pipe Exhaust System oem gmDEVELOPMENT AND TESTING: With our Porsche 996 exhaust system, 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. The analysis in 3D CAD software showed a general increase in velocity gained downstream of the mixing chamber
