It’s here! After working with Magnaflow for years, we finally got them to build us a Magnapak system for the early FOX Mustangs. They had never designed on before but now they have. We knew we wanted a very aggressive system for our new 2011 5.0 engine and now we have it. Magnaflow expects to start offering these soon. This system is a stock configuration for a FOX Mustang, there is nothing ‘special’ about it to fit our swap. We plan to worry about what is ‘custom’ exhaust up towards the headers.
