Dual exhaust systems crank up the power and performance of your diesel truck, SUV or racing rig. Naturally, a quality system performs on all levels. To illustrate, a Cat-back 4-inch exhaust not only presents a good visual, it also allows heat to dissipate at a higher speed, increasing both fuel economy and run ability. Two of the top names in systems are Magnaflow and Flowmaster. At Dualtone, we offer knowledgeable service and repair for these brands to keep your vehicle looking, riding and sounding great.
