These products use the highest quality materials and are tuned to the specific needs of the import engine to maximize flow and performance and to produce a smooth, deep performance tone. Tip and body options allow you to choose the look that fits your own personal style. Increases the flow of your exhaust by eliminating the restrictions your factory exhaust system has. Magnaflow's dyno tested exhaust system increases flow up to 167% over the OEM exhaust system. Their exhaust system reduces back pressure letting the exhaust run cooler, while creating more horsepower and torque from your engine. Mandrel bent tubing prevents backpressure, since the exhaust system is the same diameter all the way back - including all bends in the system. Maximum flow is a priority for their mufflers as well. The straight-through design uses no chambers, baffles or louvers in the muffler that interrupt exhaust flow, and creates more horsepower and torque. It creates a deep base tone outside your vehicle, without causing resonance inside. Increases exhaust flow - mandrel bent tubing, and straight through muffler design.
