a loud knocking noise can be heard when taking off in first, similar to the shuddering of a heavy duty clutch but alot louder and can definitely hear something hitting the chassis, or so it seems.

any ideas?

Exhaust ? Mines currently doing this but only on downshift..

Does it do it with the rotation of the wheels? Mine did it when a rear cv went. Sounded like someone hitting under the car with a hammer. Goes away when you go faster.

CV joints probably or u have probably ruined some teeth

Do you have a larger downpipe fitted? Mine did that, it needs some adjustment on the mounts.

yeah i have a 3' dump pipe, but have never had a problum with it and no it doesnt do it with rotation of the wheels. i'll put it on a hoist tomorrow and check the mounts, are they clearly visable or not?

cheers.
