aFe is proud to introduce the aFe MACH Force-Xp cat-back exhaust system for the 2005-2008 Porsche Boxster/S and 2006-2008 Cayman/S (987.1) that uses the OE tip. In recent testing with the OE tip, this exhaust system resulted in a max gain of 22 horsepower and 30 lbs. x ft. of torque. aFe spent countless hours of R& D 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. This exhaust system comes with a brushed finish and is 100% hand TIG-Welded for a perfect, precise fit and a easy bolt-on installation. No modifications necessary.
