# Dinan 18-23 BMW M5 F90 M5 3.25in Resonator Delete

This piece removes the hydro-formed factory resonated section and replaces it with 80mm T304 stainless steel tubing for freer flowing capabilities. In place of the factory resonator itself, 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 often in stock systems.

-   Includes X-pipe crossover made from mandrel bent tubing to promote even flow with minimum restriction
-   Deletes resonator between catalyst and rear muffler for increased volume
-   100% 304 stainless steel construction with a brushed finish
-   Easy bolt-on installation with included mounting hardware
-   3.25" (83mm) tubing replaces stock hydro-formed piping
-   Louder, smoother and fuller sound
