Coming on 10,800 miles and no noise with the step everyone has been mentioning. All I can hear is the rumble of the Magnaflow and the Airaid.
Whether you get the noise or not depends on how much backlash is in the turbine hub spline (inside your converter). Not all trucks are noisy. If your's is quiet - great! This is not a durability concern, so if all is quiet, enjoy your truck and don't worry....
