Obviously doesnt get up and go until over 2000rpm with any urgency anyhow. Its kind of a rubbing grinding kind of sound with the usually 'i dont like these low revs labouring feel'. Dont need to have it much throttle at all. noise appears just as it passes those revs. Only time i personally notice it is when i take off from first, or when the missus takes a corner in high gear.... When i drive it never sees those revs unless in first, taking off.
Has an Exedy Heavy Duty
Makes the noise in any gear id say at those revs (although havent actually tested it). Definitely 1st, 2nd and 3rd.
