Since last night when I change gear during acceleration there is almost a woosh noise when i dip the clutch. It hasn't doe. This before does anyone have any ideas as engine seems noiseier than normal.

turbo

you may have a split pipe or a pipe come loose as mr hotchef says, from the turbo

Thanks for suggestions, looked at pipes etc started up and looked under cat pipe split. Also front pipe holed. New exhaust and cat required. Hopefully sort noise out.

if you get a new cat, make sure they give you your old one back or give you a discount on the new one as they are worth a few bob even for a knackered one due to the precious metals they use inside them
