Dinan Resonator Delete Kit - 2020-2025 BMW X3M/X4M | D660-0087

The Dinan Resonator Delete Kit (D660-0087) is a performance-mandated exhaust upgrade for the 2020-2025 BMW X3M (F97) and X4M (F98), engineered to introduce a significantly more aggressive tone and increase volume over the stock system. This offering removes the hydro-formed factory resonated section and replaces it with 70mm T304 stainless steel tubing for superior flow capabilities. This system achieves a 2 pound weight savings over the stock 10 pound resonator section.

Dinan replaces the factory resonator with a beautifully crafted mandrel-bent X-pipe, which promotes even flow to both banks of tips and eliminates unwanted nuances in sound caused by uneven exhaust flow. This results in a louder, smoother, and fuller exhaust note that is befitting of the performance SAV. The tubing is 2.75" (80mm), replacing the stock hydro-formed piping.

Features:

• Resonator Deletion: Deletes the factory resonator located between the catalyst and rear muffler for a significant increase in volume and a more aggressive note.

• X-Pipe Crossover: Includes a beautifully crafted mandrel-bent X-pipe made from T304 stainless steel, promoting even flow and minimum restriction (superior to stamped X-pipes).

• Optimized Flow & Diameter: Features 2.75" (80mm) tubing that replaces stock hydro-formed piping for freer flowing capabilities.

• Weight Reduction: Provides a 2 pound weight savings (reducing the stock weight from 10 lbs. to 8 lbs.).

• Structural Quality: Built from 100% 304 stainless steel construction with a brushed finish for long-term durability and corrosion resistance.

• Installation: Designed for an easy bolt-on installation with all mounting hardware included.
