Dinan Free Flow Axle-Back Exhaust with Black Tips for F22 BMW M235i without M Performance Valence

Frequently Asked Questions
- What does the Dinan M235i axle-back exhaust fit? The Dinan M235i axle-back exhaust fits the F22 BMW M235i (2014-2016) with the N55 turbocharged inline-six, on models without the M Performance rear valence. It is a direct bolt-on to the factory mounting points, replacing the rear section of the exhaust for a louder, fuller note.
- Does the Dinan M235i axle-back exhaust fit M Performance valence cars? This version is built specifically for M235i models without the M Performance rear valence. Confirm your valence style before ordering, since a valence-equipped car may require a different rear section for proper tip alignment.
- What finish are the tips on the Dinan M235i axle-back exhaust? This version uses twin 89mm (3.5″) black ceramic clamp-on tips. A polished stainless tip version is offered as Dinan part number D660-0047 if you prefer a bright finish. The system is 100% T304 stainless steel, TIG-welded and brush-finished.
- Does the Dinan M235i axle-back exhaust add power? An axle-back exhaust is chosen mainly for sound and styling. The Dinan M235i axle-back exhaust reduces backpressure through the rear section, delivering max gains of 6hp and 5ft-lb at 6,600rpm; the primary benefit is the improved note and appearance.
- Is the Dinan M235i axle-back exhaust difficult to install? No. The Dinan M235i axle-back exhaust is a bolt-on installation using the factory mounting points, with no cutting or welding required. Mounting hardware is included to complete the swap.
