Exhaust Flap Actuator Hardware Kit

Product Details

Keep your exhaust valve functioning precisely under all driving conditions with this Genuine BMW Exhaust Flap Hardware Refresh Kit. On the street or the track, your BMW's electronic exhaust flap works hard to balance sound levels and engine backpressure. However, extreme exhaust heat cycles and harsh road vibrations frequently cause the factory spring clip to weaken or fail entirely, leaving you with a rattling muffler flap and potentially sloppy valve response. This factory-correct hardware kit brings everything back to tight tolerances. Pairing a fresh Genuine BMW fixing bow with the necessary M6 flange bolt, this kit ensures positive engagement for your valve mechanism. It's a straightforward, preventative maintenance fix that keeps your modern BMW sounding exactly as the engineers intended.
