      Video Review & Installation

      Hey, Justin with here, taking a quick look at Magnaflow’s Cat-Back exhaust system, fitting the 2005-2010 Mustang GT and GT 500. If you’re looking for a quality exhaust with great fit and finish and a tone that’s slightly more aggressive than stock, then this exhaust from Magnaflow is definitely worth checking out. You’ll first notice this two piece 2.5” mandrel bent stainless steel tubing and the chambered mufflers which are going to be most responsible for keeping the noise levels down. Finally, everything exits out these 4” polished tips. Something to keep in mind here, even though this exhaust is relatively tame with the stock headers and mid pipe, it really comes to life when you add an aftermarket set of long tubes or an off road X-Pipe, so if you’re planning on bolting some of those parts up down the road and you still want to maintain a reasonable exhaust note without too much rasp then keep the Magnaflow at the top of your list. When it comes time to get everything bolted up just leave yourself a couple of hours from start to finish using basic hand tools. Now let’s hear how Magnaflow’s Cat-Back sounds compared to our factory exhaust.

      Application. Designed as a direct bolt on for the 2005 to 2009 GT, Bullitt and Shelby GT500 Mustangs, this Magnaflow Street Cat-Back will bolt straight up to the factory Mid Pipe without any modifications required for more power and a classic muscle car 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.
