BMW M4 Performance Exhaust - Dinan - High Flow Middle with X-Pipe - 2021-2026. A precision-built midpipe that replaces the factory center section to unlock cleaner flow and a richer exhaust character.
Dinan's T304 stainless 3-inch middle section replaces the hydro-formed center run from the secondary cats to the axle-back, deleting both resonators. A hand-crafted, mandrel-bent X-pipe balances flow across banks, reducing uneven tones found in stock. Expect a louder, smoother, fuller note while retaining the factory rear muffler. It can also be paired with the Dinan axle-back for a more assertive sound. Confirmed fit with stock (including M Performance) and Dinan axle-backs; other units not guaranteed.
Features
- 76 mm (3 in) tubing vs. 70 mm stock for freer flow
- 100% 304 stainless construction; factory-like fit with hardware
- About 5 lb lighter than stock mid-section (17 lb vs 22 lb)
- G80 M3 and G82/G83 M4 fitment, model years 2021–2026
