Hey man. Sorry I'm just seeing this. I have not been on this site in a long time. So by now I'd assume you've gotten your answer. But yeah, low RPM (especially 4th gear between 1,500 and 2,000 RPM) is noisy. I thought it was a transmission problem as I have never heard it before, but after talking to some friends who have the clutch they confirmed the same noise as you and I both hear. I was pretty mad about it because I hate unnecessary noises but I've gotten use to it and the functionality of the clutch trumps the noise. So all is good. It's been two years since I've had it in the car with no issues yet. Knock on wood!
