The Dinan 16-18 BMW 340i Stainless Steel 3.25in High Flow Mid-Pipe is a performance upgrade designed to enhance exhaust flow and sound. Constructed from T304 stainless steel, this full mid-section replaces the factory center section, including both resonators, with straight-through 3.25-inch tubing. This modification not only improves exhaust flow and sound quality, producing a more aggressive tone and growl, but also reduces weight by 3 pounds, contributing to better overall vehicle performance and efficiency.
This mid-pipe is specifically designed for the 2016 to 2018 BMW 340i and F32 440i models. It is a direct replacement for the stock mid-section, intended for use with the associated Dinan exhaust system to achieve optimal sound and performance. Suitable for street and performance driving, this bolt-on upgrade offers a straightforward installation and is ideal for enthusiasts seeking a more aggressive exhaust note and improved flow on their BMW F30 or F32 chassis.
