      Video Review & Installation

      Hey guys, Stephanie with I'm going to be taking a closer look at the Kooks Performance Catback for the 2011 to '14 Mustang GT and the Boss 302. Now chances are you guys are already familiar with Kooks' products, more specifically their headers, which have been around for 40-plus years and have been one of the top options for Mustang headers. Well luckily for us Mustang owners, Kooks has recently decided to apply all those years of knowledge into making exhaust systems, including this catback for the S197. So if you guys want to see more exhaust breakdowns including companies like Kooks and many others, click the link below to subscribe to our YouTube channel and be the first to learn about all the newest products for your ride.So the Kooks catback system is designed to give your Coyote Mustang an aggressive muscle car tone combined with the same quality and fitment that you expect from a company like Kooks. That aggressive tone comes courtesy of two three-inch oval race mufflers that are constructed of durable stainless steel. Now that same stainless steel construction continues with three-inch manual bent tubing throughout the system, then exit through polished 304 grade four-inch tips.If you guys are on the new product page and you don't want to take my word for it, then be sure to check out some of the detailed customer reviews and customer submitted images of the Kooks exhaust that you will find here for each and every one of their products on the site. If you're not on the site, then just click the link below to head back and see what I'm talking about. You'll also find some very helpful installation guides there.Speaking of the install, bolting up the catback is a job easy enough for most novice mechanics. It should only take you about two hours from start to finish and includes basic hand tools. But if you should have any questions or concerns regarding the Kooks exhaust or any other product for that matter, you can always feel free to reach out to a Mustang expert here at and they'd be more than happy to lend you a hand.Now let's hear how the Kooks catback sounds compared to the factory exhaust.
