# Dinan 14-16 BMW M235i Freeflow Axleback Exhaust System - Black

Dinan engineers designed the F22 BMW M235i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Dinan also incorporates a Helmholtz chamber design that reduces resonance or"drone" at low RPM.

-   Twin 89mm (3.5") laser engraved, polished or ceramic black exhaust tips
-   Uses the factory brackets and hangers for a factory-like fitment
-   More Power: + 6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM
-   100% 304 stainless steel construction
-   Helmholtz chamber to reduce drone
-   Enjoyably louder, sportier sound
