      Hi everyone. Justin with'm going to be taking a closer look at the Magnaflow Street Catback Exhaust System fitting your 2015 Mustang GT.Now before we start breaking down the Magnaflow, I want to remind you guys to subscribe to our YouTube channel, if you haven't done so already, for more exhaust overviews and sound clips in addition to other great Mustang content.So the Street Catback from Magnaflow is just that, a perfect exhaust for the street for those of you looking for a little bit more power and sound out of your 2015 GT, or want an exhaust that you can live with every day.Now with that being said, the Street Catback probably won't win you any muffler revving contest in regards to overall volume. And if that's something you're concerned with, then you might want to check out the Competition Series Catback instead, also from Magnaflow.Either way, if you want to hear what more 2015 owners are saying about this very exhaust, then click on the link below to head back to our product page at if you're not there already.The Street's Classic 30 muscle car rumble is made possible thanks to the slightly more traditional chambered mufflers and brightly polished four-and-a-half inch tips. Now, this entire system has been constructed from 100% stainless steel including the three-inch mandrel-bent tubing, the included crossover or X-pipe, which takes place of that suitcase known in the factory exhaust system, and finally, these chambered mufflers which I just talked about.Now it is also worth mentioning that this system is considerably lighter when compared to your factory exhaust. So besides that nice little benefit of power and sound, you can also expect to shave roughly 30 pounds from your factory exhaust.Removing your factory exhaust and installing the new Magnaflow will be made much easier here in the 2015, thanks largely in part to these cars being independent rear suspension, meaning you won't have to mess with the over axle pipes.So that being said, removing that factory exhaust and getting this thing bolted up should only take you about two hours from start to finish using basic hand tools.Now it's time to hear how the Magnaflow Street Catback sounds compared to our factory exhaust.
