Product Details

The Dinan High Flow Mid-Pipe is a performance exhaust upgrade engineered specifically for 2016-2020 BMW 340i and 440i models. This mid-pipe section eliminates the factory resonators positioned between the catalytic converter and rear muffler, significantly reducing exhaust restriction while enhancing exhaust note character.

Key Features:

  • 100% 304 stainless steel construction for superior durability and corrosion resistance
  • Mandrel-bent 3.25-inch (82.6mm) diameter piping replaces stock 80mm hydro-formed sections for improved exhaust flow
  • Deletes both factory mid-resonators to reduce backpressure and free up horsepower
  • Weight reduction of 3 lbs compared to stock components (stock 24 lbs, Dinan 21 lbs)
  • Direct bolt-on installation with all necessary mounting hardware included

This mid-pipe delivers improved exhaust flow characteristics while maintaining the quality and precision fitment expected from Dinan's engineered performance solutions. The larger mandrel-bent tubing and resonator delete work together to optimize exhaust velocity and reduce restriction throughout the mid-section of the exhaust system.
