I recently found out that I don't need a catalytic converter in my car. As an environmentalist, I thought it would be a great to swap a straight pipe in place of the catalytic converter (came with the spare engine and gearbox), so I decided to do it.
First try was a bit sad. The second bolt tore its treads while Maladar tried to open it and I managed to tear half of the seal between the muffler and the catalytic converter. We decided to postpone the whole thing as we didn't have a proper seal to replace the torn one. Altough the result was more aggressive exhaust note, I needed to get it fixed before MOT inspection (again).
Finally, with huge help from Maladar and a seal from Widric, the catalytic converter was finally taken off. I thought the cell inside the converter would have been busted years ago, but no. It was like a new. Wow.
