I bought all of the bits and pieces to get this done and made a start this morning. Firstly I bought the cheaper of the two recommended drill bits thinking it should be fine for cutting through two baffles. It wasn't that good in that it only almost cut through one of the first baffles before losing teeth and becoming blunt quickly. Plenty of oil was used so I put that down to the drill not being up to much. Today I sent for the more expensive one so will start again in a couple more days. Whilst looking at the job after my drill had given up I could see straight down the pipe. It seems that the other baffles had already been removed so now I'm gonna be a straight through job albeit that wasn't my immediate intention. Put the exhaust back on and fired her up and yes there is a definite sound difference albeit the damned squeeky sound coming out of the exhaust persists. Hopefully when it is cut through properly it will go. So far so good.The other exhaust has to have the cat removed so that they match up so my next question is can this be done whilst that part of the exhaust is still connected to the pipes from the engine? I guess you have all noticed I'm not great with anything mechanical but I'm giving it a go
