your van is looking smart
sounds raspy and like its blowing from idle upto around 4500rpm.
think it will sound nice with a set of 45mm jenvey's
when you fit a new diff it may pay you to look at an astra turbo final drive. taller top end so better for motorway speeds, or a 6 speed box?
The new gearbox has got the shirt ratio final drive so I need to change it anyway and was thinking about the turbo one as there capable of 170mph or more which like you say would be alot better on the motorway..
