Hey, Justin with here, taking a quick look at Magnaflow’s Catback 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 Catback sounds compared to our factory exhaust.
