Flowmaster's systems will both improve acceleration and passing power, as well as increase fuel mileage. Every cat back exhaust system 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 USA.
