      Video Review & Installation

      Hi I’m Justin with AmericanMuscle.com, and I’m taking a closer look at the Magnaflow Magnapack catback exhaust fitting the 99-04 Mustang GT and Mach 1. The Magnapack gets its name from these two Bullitt style mufflers, which are a throwback to the classic 60’s and 70’s fastback mufflers, and the sound you get from using this exhaust reflects that. The entire system features full stainless steel construction throughout including these straight through design Magnapack mufflers, the 2.5” mandrel bent tubing, all exiting out these 3.5” brightly polished tips. Because Ford chose to weld the factory exhaust on these cars, you will need to cut it off before getting started with the install. Once you have it out of the way, getting the new Magnaflow system installed should only take you about 2 hours from start to finish. Now let’s hear how Magnaflow’s Magnapack sounds compared to our factory exhaust.
