      Hey I’m Justin with, and I’m going to be breaking down Magnaflow’s street catback exhaust system for all 2011 and newer Mustang GTs. Let’s talk about a few main features with this kit. First and most important are the mufflers that give this kit its street name, as you can see this street system uses a traditional chambered muffler, which is great at keeping the noise down, and is a far cry from Magnaflow’s other offering, the competition series, which utilizes a straight through race muffler design. Again those chambered mufflers are going to be the biggest factor in keeping the noise level down, making this one of the quieter exhausts available on the market today. So if upping the volume on your exhaust note is your number 1 priority, you might want to check out Magnaflow’s competition series instead. What you can expect from this system is a very streetable exhaust with a deep tone and practically zero drone at any RPM. The entire kit consists of 100% stainless steel construction, features 3” mandrel bent tubing, along with these chambered mufflers, all exiting out these dual 4” polished tips. Since this kit bolts directly to your factory Mid Pipe without modification, getting everything installed is very straightforward and should take you about 2 hours. Now let’s hear how Magnaflow’s street series catback sounds compared to our factory exhaust.

      Free Flowing Exhaust. Magnaflow delivers the ultimate exhaust for the 2011-2012 GT or GT500 with this Street Cat-Back Exhaust. By reducing back pressure for a free flowing exhaust, this catback produces more power and torque where it belongs - at the rear wheels.

      Classic Muscle Car Sound. The Magnaflow Cat-Back Exhaust System includes a set of two Street Series Mufflers that feature a free-flowing, straight-through perforated stainless steel core, with stainless mesh wrap and acoustical fiber fill to deliver that smooth, deep muscle car tone.

      Quality Construction. Each piece is made from 3" mandrel bent stainless steel tubing for long life and a perfect fit. The Street Series mufflers end with brightly polished 4" stainless tips, that exit in the stock locations for impressive looks.

      Application. Made to be a direct bolt on, this catback will bolt straight up to the factory Mid-Pipe without any extra modifications required on the 2011-2012 GT or GT500 Mustang to give it a deeper, classic sound.
