Dinan High Flow Middle Exhaust BMW

The Dinan High Flow Middle Exhaust is a performance mid-pipe (center section) upgrade for BMW models. It replaces the restrictive factory center exhaust section with larger-diameter, free-flowing stainless steel tubing. The result is a louder, smoother and more aggressive exhaust note. It is a popular first step in a staged exhaust build, and it works with stock exhaust systems and the matching Dinan axle-back exhaust.

Key Features:

• Builds on the factory layout with larger-diameter tubing for freer exhaust flow
• Removes the factory resonator(s) from the center section for increased volume and a sportier tone
• Mandrel-bent X-pipe crossover promotes even flow between both banks of tips, for minimal restriction and a smoother, fuller sound
• Built from 304 stainless steel for durability and corrosion resistance
• Factory-like fitment with bolt-on installation
• Pairs with the matching Dinan axle-back exhaust for a more aggressive growl

Dinan has long specialized in high-performance upgrades for BMW and other European vehicles. The High Flow Middle Exhaust gives a noticeable change in sound without the cost of a complete exhaust replacement, and the factory rear muffler can stay in place. Also known as a mid-pipe, midpipe, X-pipe or resonator delete kit.
