aFe is proud to introduce the aFe ELITE cat - back exhaust system for the 2005 - 2012 Porsche Boxster S (987.1 987.2) with H6 - 3.4L engine with aFe dual tip assembly. In recent testing with the aFe dual tip assembly, this exhaust system resulted in a max gain of 29 horsepower and 40 lbs. x ft. of torque. aFe spent countless hours of RD to develop the perfect balance of pure, race - inspired performance and in - cabin driving comfort and excitement of exhaust sound and tone during normal cruising or aggressive hard throttle. Realizing that the OE exhaust tip could be improved, aFe designed a special dual 4 polished, aFe laser - etched, 304 stainless steel, slash - cut exhaust tip assembly that is more free - flowing that the stock tip assembly. This exhaust system comes with a brushed finish and is 100 Hand TIG - Welded for a perfect, precise fit and a complete bolt - on installation. No modifications necessary.
