Very very easy to fit. It took about 1 hour (inclusing taking the old set off). The only thing you need to move is the rear brake fluid resevoir, but the exhaust system comes with a special braket to move it out the way, so it is no problem at all.

They say that you do not need either to protect any tubes from the heat (as the pipe now runs close to the coolant pipe) but for my own personal peace of mind, I ordered some heat protective tape to go around the coolant pipe. I am sure it would never melt but just in case. The exhaust kits also comes with some heat reflective pad to go under the airbox to prevent that from melting. However the airbox is right about where the pipe goes so I guess this could potentially melt without some sort of heat reflector.
