Unregistered

Hey
For the past few months my KA has had a problem getting past 40mph and I often have to keep in it in 4th gear to get anywhere. I had a mechanic out today to have a look at it and see if he could tell what was up - turns out that it needs a whole system replacement as the exhaust or cat is breaking up :(
Does anyone know who to ask, in the east of England, to get a quote for this? Also, will it be likely to fail it's MOT in this state?
Thanks

Get a few more opinions about the problem from garages, then decide which garage you want to go to. Misdiagnosis can be expensive.
