    Efficient Service

    I ordered my exhaust system on Friday and it was delivered the following Tuesday as promised. The order was correct and packaged with care. I would absolutely recommend this establishment and use them again.

    Very Happy

    This exhaust made my Mustang come alive! Love the way it sounds and the no drone technology is perfect. Absolutely no drone. I highly recommend this exhaust to anyone who is looking for an aggressive sound. Install was very straight forward and easy to do. All the pieces fit perfectly.

    Top of the line & easy install

    You can definitely tell how much time and quality went into developing this amazing system. When I opened the box everything was labeled and had a complete in detail instruction manual (in color lol). Fast and easy install, did it in my driveway with a jack and jack stands.The first start up blew me away, very nice and aggressive. Nice tone at idle and every time I get a chance to open it up and get on it, I do. Just sounds extremely aggressive and screaming down the highway. Always brings a smile to my face. The RSC technology makes taking long drives or cruise EXTREMELY enjoyable, don’t ever have to worry about that drone. I highly recommend!!!

    Best Exhaust on the Market

    I personally have had 4 different CORSA systems on my mustangs over the years because of how amazing they are. The first time I heard the Xtreme system on an S550 mustang, I knew I had to have it. The quality and fitment is superb, and the sound is unmatched. The Xtreme system is LOUD, but if you want to be able to wake the dead this exhaust is th only option.
