Sports Rear Silencer with 4 inch Black Tailpipes for BMW G30 M550i | Valve Compatible
Give your BMW G30 M550i the soundtrack and presence it deserves with this premium axle-back system from Dinan. Designed to integrate with the factory electronically actuated flaps, it delivers a refined, bass-rich note in Comfort and a purposeful growl in Sport. Crafted from robust stainless steel and finished with a pair of 4 inch double-walled black tailpipes, this rear section upgrade enhances flow, sharpens throttle response and elevates road presence without sacrificing motorway refinement.
- High quality stainless construction for long-term durability in UK conditions
- 4 inch black double-wall tailpipe finishers for a bold OEM-plus look
- Valve compatible system that works with the car’s drive modes for quiet cruising or a more assertive tone on demand
- Less restriction for smoother gas velocity and a more responsive feel
- Sound engineered to reduce low-frequency resonance inside the cabin
- Clamp-on tip assemblies for easy replacement or style changes
- Precisely tuned, motorsport-inspired character that complements the M550i’s luxury performance brief
On light throttle the note remains sophisticated and unobtrusive. Open the taps and you are rewarded with a rich, throaty bark that suits the M550i perfectly. The large satin black outlets add a purposeful finish that looks right at home on the 5 Series, while the double-wall design gives a premium visual and heat barrier.
