2014 Porsche 991 3.8L Exhaust Conversion

We installed one of the first OEM quality German made exhaust systems for the Porsche 991 Series with stainless steel headers, high flow efficiency catalyst converters, and mufflers. 
With a RSP Custom Dyno Tune on our SuperFlow AutoDyn 30 AWD Chassis Dynamometer, the power gain is approximately 10HP (flywheel) and 12 ft/lbs of torque through the entire rpm range.
