F30 F31 F32 F33 F36 BMW 330i 430i Dinan Free Flow Exhaust

Dinan’s Free Flow stainless steel exhaust for F30, F31, F32, F33 and F36 330i and 430i models is a fast-road upgrade that sharpens throttle response and adds up to +4bhp and +3lb-ft torque - no remap needed.

It’s built from 16-gauge 304 stainless, with twin 3in polished tips laser engraved for an OEM+ finish. Back pressure drops meaning better efficiency and a richer, more responsive BMW soundtrack - civilised at cruise, purposeful under load.
