Found my exhaust spigot is broken coming off of the cylinder. Are the newer models still using aluminum spigots or are they steel? At one time there was an aftermarket steel one available but I don't remember who offered it. Seems like it may be better to keep aluminum as the weakest link (rather than ruining the pipe or cylinder with a strong steel unit). I'll call the dealer tomorrow but curious if anyone has an idea on aftermarket or maybe an extra they want to sell?
