For more information, visit www.P65warnings.ca.gov.The Dinan Resonator Delete Kit (D660-0081) is a performance-mandated exhaust upgrade for the 2018-2023 BMW M5 (F90), engineered to introduce a significantly more aggressive tone and increase volume over the stock system. This component removes the hydro-formed factory resonated section and replaces it with 80mm T304 stainless steel tubing for superior flow capabilities.
Dinan replaces the factory resonator with a beautifully crafted mandrel-bent X-pipe, which is the focal point of the system. This sophisticated 'X' crossover promotes even flow to both banks of tips, eliminating the unwanted nuances in sound often caused by uneven flow in stock systems, resulting in a louder, smoother, and fuller exhaust note. This upgrade ensures the stately M5 sounds every bit the performance sedan it is.
Features:
-
Resonator Deletion: Deletes the factory resonator located between the catalyst and rear muffler for a significant increase in volume and a more aggressive note.
-
X-Pipe Crossover: Includes a beautifully crafted mandrel-bent X-pipe made from T304 stainless steel, promoting even flow and minimum restriction (superior to stamped X-pipes).
-
Optimized Flow & Diameter: Features 3.25" (83mm) tubing that replaces stock hydro-formed piping for freer flowing capabilities.
-
Structural Quality: Built from 100% 304 stainless steel construction with a brushed finish for long-term durability and corrosion resistance.
-
Installation: Designed for an easy bolt-on installation with all mounting hardware included.
