As an added bonus the tips are etched with the "MBRP" logo for true custom styling.

      Direct Bolt-On Installation. Engineered to be a direct upgrade replacement for your Mustangs factory exhaust, the MBRP Race Cat-Back Exhaust Kit easily bolts up in the stock location with no modifications required.

        I love it, the neighbors...not as much...

        The fit and finish was good. Routing it was decent. I took the advice of others here and took it to a friends shop and had it installed using a lift. It is loud and I really like it, but I live in a condominium complex with a majority of the residents older than 60 and many of them are not as happy about it as I am.

        one of the best

        This is one of the better exhaust I have in install in a long time. The fit and finish is can compete with more higher dollar exhaust. But i do recommend if you have access to lift use it but if you use jack stands take off the passenger rear tire give u more room to work and you may need a small pry bar and rubber hammer to get that passenger side pipe on because of the way the diff is set up . But over all it was easy install love the sound it makes and drone is at a minimum

        4 2007 GT - Josh757 Installation Time: Afternoon

        Sound of the Past

        This exhaust, from the moment I heard it took me back to my grandfathers garage, and back to the 90's. I use to listen to him tinker on his original Boss mustang, and I swear the moment I heard the exhaust start up it took me back to that garage. My grandfather has passed but I feel his hand guide mine as I pick car parts, and work on my own mustang. And I know as long as I have my mustang a part of him is with me. The exhaust when it first sounded off after being installed on my 2007 S197 gt I knew my grandfather was pleased, I was pleased, and my Mustang sounded perfect.

        better off spending a little more for better product

        All bends in pipes are just far enough off that you can't get the tips to line up, it hits the rear if you position it so that the tips are in the center of the cutouts. Other than that it sounds good has nice tone, just wish it would fit right. You would be better off spending a little more on another kit that fits better.

        5 2008 GT500 - BWatson Installation Time: Shop Install Installation Cost: $100-$250

        Just what I needed

        When I got my GT500, I was disappointed in how quiet it was. Listened to a lot of exhaust clips and had a very hard time picking. While this cat back did not have a sound clip, the advertised gains were what sold me. Tried to install it in the driveway but without taking apart the whole rear end, I could not get the massive 3" pipe fed through, and ended up taking it to a shop for install. This exhaust seriously woke up my Mustang. It is loud and aggressive so if you want quiet, do not get this exhaust. It can easily set off car alarms but I love how loud it is. I have not put it on a dyno, but I believe the advertised gains as it was quite a difference in performance.
