      Hey, everybody. Justin with, here with my complete breakdown of the Magnaflow Competition Series Catback Exhaust System fitting your 2015 Coyote powered GT.Magnaflow has definitely made a name for themselves over the past 30 or so years, as one of the best in the biz, thanks largely in part to their quality build, great sound and perfect fitment.The Competition Catback from Magnaflow will no doubt be one of the more aggressive systems available for your Coyote Powered GT, and will certainly be much more aggressive when compared to the Magnaflow Street Catback.The main difference in sound is simple; it's in the muffler here. This is a straight-through design which will not only free up a lot of power, but also give you that very tough sound a lot of us Mustang owners are after.Getting into some of the specifics, you will notice the competition includes 3-inch mandrel bent tubing from the included crossover, or X pipe, which does take the place of that factory suitcase portion of your exhaust, along with these straight-through competition mufflers and out the brightly polished, rather large, four-and-a-half inch tips.I do want to point out that this entire kit has been constructed from 100% quality stainless steel. So besides looking good for years to come, you're also going to save a few pounds when compared to your factory, rather hefty, exhaust there.Now guys, if you do want to see more detailed photos of this exhaust including some customer reviews, then just click on the link below to head back to the product page, if you're not already there.Since the 2015s are equipped with IRS, removing the old exhaust and bolting up the new Catback should be a lot easier than previous generations, thanks largely in part that you don't have to deal with those over-axle pipes. With that being said, removing that factory exhaust and installing the new Competition here from Magnaflow, should only take you about two hours using basic hand tools.Now it's time to hear how the Magnaflow Competition Catback sounds compared to our factory exhaust.
