# Dinan 17-21 BMW 230i Freeflow Axleback Exhaust System - Polished

Dinan engineers designed the BMW F22 230i 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. Like all Dinan exhausts our 230i Free Flow Axle-Back Exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone.

-   Twin 76mm (3") laser engraved, polished or ceramic black exhaust tips
-   Uses the factory brackets and hangers for a factory-like fitment
-   Drone abatement technologies used to reduce cabin resonance
-   More Power: + 4 HP @ 6600 RPM, + 3 LB-FT @ 6600 RPM
-   100% 304 stainless steel construction
-   Enjoyably louder, sportier sound
