How it sounds and feels
In Comfort, it is civilised and hushed for commuting and motorway miles. Open the throttle and the valves allow extra flow, giving a deeper, more assertive note that suits the 750i perfectly. Outside the car it has a mature, bass‑rich character without the harshness. Inside the cabin it stays composed thanks to Dinan’s focus on resonance control.

Customers love the OE‑plus look, the quality welds and materials, and the way it wakes up the car without spoiling daily refinement.

Construction and finish
Dinan uses 304 stainless throughout with 16 gauge tubing for long‑term durability in UK conditions. The design keeps factory tip locations for a sleeper aesthetic and integrates with the car’s valve control so you keep the quiet mode for early starts and a freer flow under load.
