Good news on the workshop, Jon. I think you have hit the nail on the head that a run of mild steel exhausts would dent the demand enough to make a second run in stainless unviable, and that everyone would prefer stainless even if it costs more. Happy to be corrected on that via feedback, but I don't really want to stand behind a run of mild steel exhausts and have them take up permanent residence in my garage while everybody waits for the stainless version. So my money would be on a run of five in stainless with the flexi-joint as Barry described, either flanged or sleeved as you think appropriate. If you could do them for £300 each, then I reckon it is worth going ahead. And Pawel – I expect you will get better answers from people who know a lot more than me, but I was told that a MkI Civic back box will fit, but that the entire exhaust will be too short. Unfortunately I don't know just where the inches are lost. I was also told that a Mk2 Civic exhaust is longer and might fit, though.
