My pride and joy is a 2001 Twinnie phase 2/CF3 and as many other CF3 owners are finding, the flexi pipe on my down pipe is on its way out. I am toying with the idea of replacing the whole lot with the Alfaholics down pipe which comes minus the twin pre-cats. In anticipation while I had the bonnet open and tool kit out today I tried the nuts on the manifold/down pipe join. Three were easy to get to and came undone no problem. The 4th I couldn't even get my hand to let alone a spanner or socket. Any suggestions? It is the one at the back in the middle of the manifold nearest the engine.
