BMW M340i Performance Exhaust - Dinan - Axleback - Polished - `20-`24. A free-flow axle-back that gives your M340i a deeper, meatier tone while preserving day-to-day manners.
Crafted from TIG-welded T304 stainless steel, this system increases flow with 76 mm tubing (vs 70 mm stock) and employs twin 76 mm valves for balanced, responsive sound. The factory actuator is reused and a second valve added: open under load it delivers a straighter, harder-hitting note; closed it routes gases through the muffler to the inner tips for quieter cruising. Cabin comfort is maintained with effective drone control, and four 102 mm polished, laser-engraved tips provide a purposeful finish.
