Transform the auditory and visual appeal of your BMW X3 M40i or X4 M40i with the Dinan Valved Cat-Back Exhaust System—a precision-engineered solution for enthusiasts seeking the ultimate in performance, sound, and style. This system not only amplifies your driving experience with a commanding sound profile but also elevates your vehicle's aesthetics with a bold quad-tip design inspired by M-performance standards.

Engineered for a straightforward, hassle-free installation, the Dinan Valved Cat-Back Exhaust requires no cutting or welding and uses factory mounting points for seamless integration. Constructed from 100% T304 stainless steel with TIG welding and a hydroform-free design, this exhaust system ensures exceptional durability and a premium finish. The standout feature is its transformation from dual OEM slip tips to a stunning quad-tip setup, available in polished stainless steel or black ceramic finishes, each bearing the iconic Dinan logo.

Beyond its striking design, the Dinan system is built to deliver auditory excellence. By removing the restrictive central resonator and incorporating an enlarged single-pipe layout, the exhaust achieves improved flow and weight reduction. The Helmholtz-equipped muffler ensures a signature deep Dinan rumble, while drone abatement technology provides a comfortable in-cabin experience. The factory valve functionality is retained, allowing for dynamic sound control—refined and subdued during low RPM cruising, or aggressive and exhilarating at high RPMs. Pair this system with an optional valve remote for complete sound customization.

Designed for the discerning driver, the Dinan Valved Cat-Back Exhaust optimizes both performance and acoustics, delivering up to +6 HP and +5 lb-ft of torque while being 7 pounds lighter than the stock system. This upgrade is perfect for those who demand unparalleled performance without sacrificing civility or style.
