BMW X5 M Competition Performance Exhaust by Dinan — Axle-Back, Freeflow, Valved, T304 Stainless with Polished Tips (2020–2026). Tuned to enrich the V8 voice while preserving day-to-day comfort.
Dinan increases flow with 83mm tubing (vs 80mm stock) feeding a muffler that blends absorption and reactive technologies to lessen backpressure. Factory valve control is retained for subdued cruising and full authority under throttle, while drone‑abatement tuning tempers cabin resonance. T304 stainless steel, TIG‑welded and brush‑finished, finishes with quad 4.5 in. double‑walled polished tips laser‑engraved with the Dinan logo. Factory-like fitment with included hardware and gains up to +6 hp and +5 lb‑ft.
