In place of the factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes which are commonplace in the market. 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.\nStainless Steel - 3\" - G30\nOnly confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems.

Designed for the G30 platform, this full mid-section kit removes the hydro-formed factory center section and resonator, replacing them with larger 3-inch T304 stainless steel tubing for improved airflow and a more responsive exhaust system. The result is a louder, smoother, and fuller exhaust note with a sportier character.\u003cbr\u003eThe factory resonator is replaced by a precision-crafted X-pipe made from mandrel-bent tubing. Unlike stamped X-pipes, this design promotes more even exhaust flow between both banks, helping reduce uneven sound characteristics while minimizing restriction. The X-pipe also serves as the visual and functional focal point of the system, complementing the increased volume created by resonator removal.\u003cbr\u003eBuilt for durability and straightforward installation, the Dinan D660-0080 uses 100% 304 stainless steel construction and includes the required mounting hardware. This bolt-on middle exhaust is confirmed to fit with the Dinan Free Flow Axle Back and the stock exhaust system. Fitment with other axle-back systems is not guaranteed. Professional installation is recommended to ensure proper alignment and secure installation.
