When the Hurst engineers needed an exhaust system that would not only sound good but also out-perform all others on both naturally aspirated vehicles and especially on force inducted (turbo or supercharged) vehicles; they went to the industry technology leader. Flowmaster has not only supplied the US military with technologic support but also holds patents on many truly innovative designs that make engines not only sound good - but perform. Designed and built in the USA of stainless steel and incorporating Flowmaster®s patented laminar flow technology, these beautiful mandrel bent axle-back systems employ vehicle specific tips that feature the famous Hurst logo.
