Akrapovic Evolution exhaust valve rattle?

[Zmaj]

Anyone had a problem with Akrapovic Evolution exhaust valve rattle on F10 M5? Its most noticeable when vehicle is started. Originally thought it was the tip but after taking them off passenger side valve shaft is loose, while the driver side is firm and makes no rattling sounds.

Thank you!!

Also, here is the exact part I'm referring to for visual purpose.

FWIW, no rattle here. Without the ASD the Akra sounds awesome! Looks like there is some adjustment in the rod. At valve close position make sure it's fully closed all around. I think that may fix your problem

at valve position its fully closed, problem is the slack in the rod and rod is not adjustable to be tightened / serviceable.. Akra took care of the problem with a replacement, just simply excellent service. Big thumbs up!

Was the under warranty, or out of warranty?
