    Video Review & Installation

    Justin here from, breaking down Magnaflow’s Competition Series Cat-Back exhaust for the 2011 and newer V6 Mustang. This is probably one of the most aggressive kits available for the 3.7L V6, thanks in part to that 2.5” mandrel bent piping, straight through those competition series mufflers, and out the dual 4” polished tips. Now that straight through design is going to totally eliminate a lot of back pressure, making for big power gains, especially in the upper RPM range. Despite that gain in power, you can expect an extremely aggressive exhaust note, so for someone who’s trying to stay under the radar, this might not be the kit for you. The entire kit features 100% stainless steel construction, all the way down to those dual 4” polished tips. You can expect to have everything installed in about two hour’s time. Now let’s hear how Magnaflow’s Competition Series Cat-Back sounds compared to your factory exhaust.
