Well I do arc welding and mig welding (if i do any mig i use someone elses welder) for a living... pipeline welder.

I just let the muffler guys do it. Arc would just melt it. Tig or mig is fine, tig mite be not powerful enough (you mite want to clamp it also) tig doesnt work well with thigs that vibrate. Oxy-acetylene is what you would use to cut with, you could also weld with it, very cheap welder. I have one, but just welding up a muffler isnt worth the cost of acetylene
