BMW 430i Performance Exhaust - Rear - Dinan - Axleback Freeflow - Polished (2021–2024). A precision axle-back built for factory-like fitment and a deeper, sportier tone without drone.
Constructed from TIG-welded 100% T304 stainless steel, this system uses factory cut points and mounts for a straightforward install. Optimized flow helps reduce back pressure, with verified gains up to +4 hp and +3 lb-ft. Dual 102mm (4") polished, clamp-on tips with a laser-engraved Dinan logo make the upgrade clear, while retained OEM valve control keeps volume civil when desired. 430i fitment is confirmed for the G22 coupe; G23 convertible and G26 Gran Coupe are untested and may have underside bracing interference.
