Hello If I mount Magnaflow 3in cat-back on my Mustang GT 2002 what is best in X or H pipe to complet the exhaust ?


  • The Magnaflow Competition Cat-Back Exhaust - 3in. for the 99-04 GT, Mach 1, Bullitt will sound great with either the H or X mid pipe of your personal choice. The H will deep and throaty toned and the X pipe will be High pitched and Raspy toned. This Magnaflow Cat-Back will be a 3in which will require a 3in Mid pipe to properly bolt up together.
