in California, I wouldn't pay more than $80, if you know the guy, its about $40-$60, this is when you should start getting familiar with muffler shops and then you bring them people after you come for your work,thats how I did it, now most of my welding needs are about $20 for my car, and about $40-$60 for friends I bring in(even some major stuff)
EVILRB beat me to it, pretty much same thing he said
