Description
The debate over the top performance SUV often concludes with the BMW X5M (or X6M), reigning supreme. These mighty vehicles combine intimidating size with surprising agility, making them perennial category kings. However, their stock exhaust note falls short of true glory due to refinement and respectability constraints. Enter Dinan and their Valved Axle-Back Exhaust upgrade, preserving these important characteristics while unleashing the full vocal range of all 8 cylinders. With Dinan, the beast has found its glorious bark.
To achieve the desired sound volume and tone fitting for the F9x X5M/X6M, Dinan enlarged the tubing to 83mm, allowing for freer flow throughout the entire system compared to the stock 80mm. This larger tubing feeds into a muffler designed with absorption and reactive technologies, improving exhaust flow and reducing backpressure. The result is increased power output and a sporty sound that can be civilized or pleasantly aggressive when you desire. The computer-controlled exhaust valves retain their function, limiting noise during low-speed driving and fully opening during high-load conditions, enabling free flow and enhanced sound as most gases bypass the muffler. As expected from Dinan exhausts, the X5M/X6M free flow exhaust is engineered to minimize low-RPM drone, ensuring an intimate cabin experience without excessive noise. With Dinan's exhaust system, you can enjoy an aggressive tone while maintaining the luxury SUV's civility - the perfect combination for those with a penchant for aggressive behavior.
Sound is not the only aspect that received modifications. The Dinan F9x X5M/X6M exhaust is skillfully crafted entirely from T304 stainless steel, ensuring durability and a visually appealing appearance. The system undergoes TIG welding for the best color and visual finish, resulting in an immaculate look out of the box. Attention to detail extends to the exhaust tips themselves, featuring massive quad 4.5" clamp-on, double-walled, polished stainless steel tips with laser-engraved Dinan logos. These tips not only fill up and accentuate the factory cut-outs but also exhibit an extremely aggressive yet refined styling, commanding attention even before the exhaust is heard.
