Description
Unlock the true potential of your 2020-2023 BMW X5M/X6M with the Dinan Valved Axle-Back Exhaust. When it comes to performance SUVs, the BMW X5M (or X6M) reigns supreme, commanding attention with its imposing presence and astonishing agility. However, there has always been a missing element when it comes to the auditory experience. While the stock exhaust note is respectable, it fails to unleash the full glory of the vehicle's 8-cylinder engine due to refinement and respectability constraints. That's where Dinan steps in, offering an exhaust upgrade that retains the important characteristics of refinement and respectability while allowing the full symphony of all 8 cylinders to surge through the system and showcase their vocal talents. With Dinan, the beast has found its bark, and it is nothing short of glorious.
To achieve the desired sound volume and tone that befits the F9x X5M/X6M, Dinan enlarged the tubing to 83mm, providing freer flow throughout the entire system compared to the stock 80mm tubing. This larger tubing leads to a muffler that exemplifies Dinan's exhaust design philosophy, incorporating absorption and reactive technologies to improve exhaust flow and reduce backpressure. The result is an increase in power output and a sporty sound that is civilized when desired but pleasantly aggressive under hard acceleration. This is made possible by the retained computer-controlled exhaust valves, which limit noise during low-speed driving and open fully during high-load conditions, allowing for unrestricted flow and a more pronounced sound as the majority of the gases bypass the muffler. Additionally, Dinan exhausts are engineered to reduce low-RPM drone, ensuring that the cabin remains intimate without being overwhelmed by excessive noise. With the Dinan exhaust equipped on the X5M/X6M, you get the best of both worlds: an aggressive tone and sound combined with refined civility—a perfect fusion for a luxury SUV with a penchant for assertive behavior.
The modifications to the exhaust system go beyond sound enhancement. The Dinan F9x X5M/X6M exhaust is meticulously crafted from T304 stainless steel and TIG welded, guaranteeing not only exceptional performance but also a visually appealing system. The entire system is brush finished to ensure a pristine appearance right out of the box. Attention to detail extends even to the exhaust tips, which are massive quad 4.5" (114mm) clamp-on, double-walled, polished stainless steel tips with laser-engraved Dinan logos. These tips perfectly fill and accentuate the factory cut-outs, showcasing an extremely aggressive yet refined styling that will undoubtedly make heads turn even before the exhaust note is heard.
