Overview

Dinan High Flow Mid-Pipe for BMW 340i / 440i 2016-2020

Instructions for Part# D660-0057

Note:

Only confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems. Fitment with other axle back units is not guaranteed.

The Dinan High Flow Mid-Pipe for the F30 340i and F32 440i transforms the factory sound into a bolder, more aggressive tone, and enhances it even further when paired with a Dinan exhaust. This mid-pipe system replaces the factory center section and removes both resonators, incorporating 3.25" mandrel-bent T304 stainless steel tubing for improved flow, an amplified exhaust note, and a 3-pound weight reduction over the stock setup.

Key Features:

Enhanced Sound:
- Deletes both resonators, delivering a more aggressive exhaust note.
Improved Flow:
- Replaces stock hydro-formed 80mm piping with 3.25" (82.6mm) mandrel-bent stainless steel for optimized exhaust flow.
Premium Construction:
- Built from 100% T304 stainless steel for durability.
Weight Reduction:
- Weighs 21 lbs compared to the stock 24 lbs.
Easy Installation:
- Bolt-on design includes all necessary mounting hardware.
