M550I MIDDLE EXHAUST

The Dinan Middle Exhaust for the G30 M550i introduces a more aggressive tone and an increase in volume over the stock system. This full mid-section kit removes the hydro-formed factory center section, including the resonator, and replaces it with larger 3" T304 stainless steel tubing for freer flowing capabilities. In place of the factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction. This sophisticated 'X' is not only the focal point of the system in terms of aesthetics but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is found in stock systems. Along with the inherent benefit of increased volume by removal of the resonator, the Dinan Middle Exhaust for the G30 M550i produces a louder, smoother and fuller exhaust note. Only confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems. Fitment with other axle back units is not guaranteed.
