Exhaust Masterclass … so let’s guess the problem? Photo 1 shows a catalytic converter fault. Using a borescope (camera on a stick) it looked fine at first but the oxygen sensor readings don’t lie. It was like it wasn’t there and in this condition it may have well not been. Completely falling apart and cracked in half. New exhaust section was needed and now back to new with no “check engine” light. Photo 2 shows a new muffler in the back of the Tesla. The boys at Hannam St Exhausts clearly don’t share my sense of humour…
