    Review & Install Video

    Hey it’s Justin with, and I’m taking a closer look Magnaflow’s Magnapack exhaust system, fitting all 05-09 GTs and all 07-09 GT500’s. The name Magnapack plays homage to that classic muscle car sound of the 60’s and 70’s, specifically the glass pack mufflers that were on just about anything with a V8. Anyone that has heard a glass pack before knows that the sound is certainly unique, and Magnaflow has done their best to recreate that nostalgic sound, with the use of their straight through design Bullitt style Magnapack mufflers. Like any other Magnaflow system, the Magnapack is built extremely well, and looks as good as it sounds, as for the construction, well, the Magnapack is made from 100% stainless steel, including the small amounts of 2.5” mandrel bent tubing, those brightly polished Magnapack mufflers, and finally the unique styled 3.5” tips, which do exit out of the stock location. Since this is an axle back the install shouldn't g’ve you too much trouble, and only take an hour in the driveway using basic hand tools. Now let’s hear how the Magnapack from Magnaflow sounds compared to our factory exhaust.

    Free Flowing Exhaust. Magnaflow delivers the ultimate free flowing exhaust for the V8 powered S197 Mustangs with the Competition Axle-Back Exhaust. By eliminating power robbing restrictions, more horsepower and torque is produced where it belongs - at the rear wheels.

    Aggressive Muscle Car Sound. The Magnaflow Competition Axle-Back Exhaust System features a set of two straight through bullet-style competition mufflers to give your Mustang the loud aggressive exhaust note of the muscle cars of yesteryear.

    Quality Magnaflow Construction. The Magnaflow Competition Axle-Back System is constructed from 2.5" mandrel bent stainless steel tubing for long life and a perfect fit. The system features (2) competition straight-through mufflers along with (2) brightly polished 3.5" stainless steel tips that exit from the stock location for impressive good looks.

    Application. Made as a direct bolt on, this Magnaflow Competition Axle-Back Exhaust System will bolt straight up without any modifications required on the 2005 to 2009 GT, Bullitt and Shelby GT500 Mustangs to give it a deep aggressive sound.

    Technical Note: Americanmuscle recommends adding the 2005+ Mustang 304 Stainless Steel Exhaust Hanger Kit from the drop down option above, to provide more strength, stability and a cleaner installed appearance. If you have a 2007 Mustang you may need the kit for correct installation.

      Not impressed

      While the fit and finish are perfect, the sound is disappointing...not as loud as I had hoped for. I agree with the last review...I feel like I wasted my money.

      Love the sound

      Low frequency rumble, not louder than stock at idle, like the efficient flow thru design

      The sound is AWESOOME. However, the fit was far from perfect. No matter how many times I loosened and tightened the bolts, it was never even. The problem was with the factory hangers. I had to take it to the muffler shop to have them heat, bend and adjust the hangers for the perfect fit. Overall, these are great mufflers that get attention.

      Not very loud

      It has a nice rumble sound but not much louder than the factory one. I feel I wasted my money on this because my factory exhaust was in fine condition I only replaced it for some tougher sound but failed with this system.
