How hot does casing/exhaust get?
Am in process of fitting it to the 45 degree bulkhead under seat, there is existing foam insulation internally and major amount of sound deadening stuff externally!
Is it safe to leave these both in place? Internal stuff is probably shite so can go tbh. Should I ensure that no exhaust pipe is touching sound deadening matting thingy stuff?

Fast "correct" answers worth a pint...wanna get it finished this eve...
