BMW M3 Performance Exhaust - Dinan - Valved Axle Back - Polished - 21-26. Built for the G8x M3/M4, it gives your car a deeper, richer voice while preserving factory valve control.
Developed through extensive testing, the system uses 76mm tubing (vs 70mm stock) for freer flow and reduced backpressure. With valves closed, gases route through the Dinan muffler for a refined, subdued note; when open, a near straight-through path delivers assertive sound. Built from 100% T304 stainless steel, TIG welded and brush finished, it reuses OEM actuators, sheds about 6 lb, and can add up to +6 hp and +5 lb-ft.
