Long story short I need to get my resonator welded because it cracked at the welds. Any one know of a place I can take it to get it welded? Exhaust shop, performance shop, side jobs etc...? (Stainless steel)

I live in Morton Grove so preferably something around my area or North Chicago.

Your help is appreciated,

Here is a pic, its the dark split on the resonator that needs to be welded up.
