Hey mate, just got my 2006 4.2 with 90,000 ks back from the mechanics, got him to check the valve clearances only and some far there is no sound what so ever.
3 of the valves needed a slight adjustment......not saying that it will fix yours as it may be something else, letting you know anyway

Straight through section on. Now it sounds like a 4.2 ...

Good to hear yours is quiet now. I am pretty confident that mine is the plunger mechanism on the pump. Was just with Mudski before and his sounded quiet just like mine before his amplified greatly. I think my valves are overdue to be adjusted anyway so, I guess it'll all narrow it down sooner or later.

New straight through pipe sounds awesome! I can't get any unpleasant drone or noise inside the cab, but early days yet... And I have gained a little bit of up and go as well which is a bonus.
