Pipe rust removal

Undo the 2 small nuts on the head (thing that spark plug screws in) then undo the bolts on the mount by the wheel an itll come straight off

 

ok do i need any specific tools ?

 

Erm think there 8mm bolts (dont hold me to that lol) at the exhaust manifold, then a wrench or spanner to undo the 2 bolts holding it on at the mount an its done no special tools needed. Only takes 10 mins
