Funnily enough, hoping to do the same job myself this weekend. Got a couple of quick questions for you Ben.
Did you find there was enough room with the car just on ramps, or did you try and raise the front of the car a bit as well? And, did you use any exhaust paste on any of the couplers/gaskets?
I have also read elswhere that it is a good idea to use stainless bolts and split washers and copper nuts, as this makes it easier to remove said fixings later on for removing cat etc. Has anyone got experience of using these, as I am a bit concerned about overtightening and stripping the thread on the nuts. Torque settings for example?
