Exhaust manifold is easy enough, however the dipstick holder needs to be removed and the coolant overflow needs loosening off to put the manifold in the correct position. I couldn't get the manifold bolts to bite onto the manifold tightly enough, possibly because they are slightly too long, but adding an extra washer to each bolt solved the problem.
Next, the back end of the pipe needs trimming to allow the silencer to fit and allow it to be removed without having to remove the rear wing. I measured 60mm back from the weld and cut there. Once done, the silencer is offered up to determine the correct position for the exhaust mounting bracket. The exhaust bracket is mounted with 2 x M10 bolts through the floor and one through the side of the lowered floor.
The front of the silencer needs a slot cutting to allow it to clamp round the manifold pipe. After this, I stop-drilled the slot to relieve the root-bending stresses and prevent it from propagating any further (finally, 3 years studying engineering pays off!):
Once prepared, the whole lot was bolted together (without paste) and that's the exhaust done.
