BMW M240i Performance Exhaust by Dinan (2023–2026). A valved axle-back in T304 stainless with quad black 102mm tips that delivers a deeper, meatier tone without unwanted drone.
Engineered for the G42 M240i, it adds a second valve and ups tubing to 76mm (vs 70mm). Open valves route flow to the outer pipes for an aggressive character; closed, gases pass through the muffler and exit the inner tips for refined cruising. Factory electronics are retained.
Features
- Twin computer-controlled 76mm valves; 30% less restrictive than OE.
- 76mm tubing for increased flow (stock 70mm).
- Quad 102mm (4") straight-cut, double-walled, black ceramic coated tips.
- Reuses OE actuator with a second actuator added; factory-like fitment, hardware included.
- Approx. 4 lb lighter; measured gains of +6 HP / +5 lb-ft @ 6600 RPM.
