Some sort of hiccup seems to have occurred here with Fernando's GTL, up on the ramps. Unsurprisingly, it's that fussy little bit of pipe in front of the exhaust back box, which always seems to be a problem on later models that have the box at the rear end of the car (some R4s have the tail pipe in front of the rear wheels). In the worst scenario, you may need to replace both the back box and middle section of the exhaust to cure this problem, at great expense, as has happened at least once with my car in the past. At best, you might just get away with some mending of the join, if it isn't in a bad state.
