BMW F22 M235i Free Flow Stainless Exhaust by Dinan — without M Performance rear valance
Looking for the best BMW M235i exhaust upgrade for the F22 platform? The Dinan Free Flow Stainless Exhaust for the BMW F22 M235i and M235i xDrive delivers the sound, quality and performance you expect from a premium performance exhaust. This F22 M235i cat back style rear section reduces backpressure to improve flow for enhanced throttle response and power, while the tuned Helmholtz chamber reduces cabin resonance and drone at low RPM. Civilised on the commute, aggressive and sporty under hard acceleration — exactly what an M235i performance exhaust should be.
Built from 100% 16 gauge 304 stainless steel, this BMW 2 Series performance exhaust is engineered to last and to fit perfectly using the factory hangers. The twin 89 mm ceramic black exhaust tips complete the look, filling the standard rear valance with a tasteful, high performance finish. This version fits cars without the M Performance rear valance.

What it feels and sounds like
On our own M235i and across customer cars, the Dinan system delivers a deeper, richer tone with a noticeable improvement in responsiveness. Around town it remains civilised with minimal cabin drone thanks to the Helmholtz design, while wide open throttle brings a crisp, sporty bark that suits the M235i perfectly.
