Dinan Valved Cat-Back Exhaust System for BMW X3 M40i / X4 M40i 2018-2024

Transform the driving experience of your BMW X3 M40i or X4 M40i with the Dinan Valved Cat-Back Exhaust System. Designed for the discerning enthusiast, it delivers a richer, more aggressive exhaust note while maintaining the versatility of factory valve control—allowing you to switch between a refined cruise and an exhilarating roar. Crafted from premium T304 stainless steel and featuring an authentic quad-tip design, this direct bolt-on system not only enhances sound and performance but also adds striking visual appeal to your vehicle’s rear profile.

Key Features:

  • Dynamic Valved Sound: Retains factory valve functionality—enjoy a quiet, civilized tone when closed and an open, aggressive roar when you want full auditory excitement.

  • Authentic Quad-Tip Design: Equipped with four individual 3.75-inch polished or black ceramic tips for a bold, M-inspired aesthetic, without using faux "Y" outlets.

  • Direct Bolt-On Installation: Requires no cutting or welding. Uses factory mounting points for a straightforward fit on both pre-LCI and LCI models.

  • Superior Build Quality: Fully constructed from TIG-welded 100% T304 stainless steel for durability and corrosion resistance.

  • Enhanced Performance & Flow: Features larger 83mm diameter piping and removes the central resonator for increased exhaust flow, contributing to gains of +6 HP and +5 lb-ft torque.

  • Drone-Free Comfort: Incorporates Helmholtz resonance technology to eliminate unwanted cabin drone while cruising.

  • Weight Reduction: Saves approximately 7 pounds over the stock exhaust system.

  • Factory Fit & Compatibility: Includes all necessary hardware for seamless integration and a perfect fit.
