Well the answer is NO !!!!! Took the 4200 with my x pipe and rear straight throughs to get changed over following a phone call :yes sir just bring it down.
The outcome was they were too scared to break any thing.
How hard can it be?
Try round the local garages, they should be able to help you. All you need is a ramp, a socket set, a couple of spanners and a hammer. If it comes apart easily, it shouldn't take more than a couple of hours.
