    Flowmaster Cat-Back Exhaust Systems are designed with the latest technology to provide the best possible performance from a Flowmaster Muffler. They improve acceleration, passing power, and fuel mileage. Every cat-back exhaust is individually engineered and dyno-tested for each application. All tubing is mandrel bent for the best possible exhaust gas flow and fabricated from 409S stainless or aluminized steel for corrosion resistance. Made in the USA.
