Lasts for about 15 - 20secs then as the revs drop it's extremely quiet. Is that normal or consistent with other 370's?

What you are hearing is the cams being advance to reduce emissions in cold start, both cams will advance 35 degrees for about roughly 10 seconds and that what causes the rough sound like a exhaust leak .

Hope this helps
