I have a decatted R26 and the MoT is coming up. I have the original cat but did not remove it. i hear that it is a right PITA to replace and 'unreplace'. My options are then: Fail the MoT Spend a day (which I am sure it will end up taking me) refitting it and then another reversing it Cutting in and welding in a random replacement cat between the front seats which I have seen on other Meg groups. They all seem like a PITA. Why is the std cat such a PITA to fit? I heard you have to take the driveshaft out?
