Dinan Resonator Delete Kit for BMW X3M / X4M 2020-2025

The Dinan Resonator Delete Kit for the F97 X3M and F98 X4M upgrades the exhaust sound profile, delivering a more aggressive tone with enhanced volume. This kit replaces the factory resonated section with an optimized, mandrel-bent X-pipe made from T304 stainless steel, creating a distinct exhaust note that is smoother, fuller, and better suited to the high-performance nature of BMW’s SAV (Sport Activity Vehicle).

Key Features:

• Enhanced Acoustics:

  • Louder, smoother, and fuller exhaust note for a dynamic sound experience that aligns with the performance of the X3M and X4M.

• High-Flow X-Pipe:

  • Includes a precision-crafted X-pipe that ensures even flow to both exhaust tips, minimizing backpressure and producing a balanced, aggressive sound compared to standard stamped X-pipes.

• Improved Flow & Performance:

  • 2.75" (70mm) mandrel-bent T304 stainless steel tubing replaces the factory 70mm hydro-formed piping, promoting freer exhaust flow for improved response.

• Weight Reduction:

  • Lighter than the stock system, reducing weight from 10 lbs. to 8 lbs. for a slight performance advantage.

• Durable Stainless Steel Construction:

  • Built with T304 stainless steel and finished with a brushed look for both durability and a high-quality aesthetic.

• Easy Bolt-On Installation:

  • Designed for a seamless fit, this kit includes all necessary mounting hardware for a straightforward installation process.
