My ECHO has an exhaust leak right where one of the hangers is welded to the pipe. This pipe extends from the manifold to the muffler and has an integrated catalytic converter. The pipe is original and despite the miles is still relatively substantial and I'm not throwing any cat codes or anything. Would it be a good idea to try and get this repaired rather than buying a new converter? The OEM converter/pipe is $1000 and aftermarket ones are less of course. If a repair is a good idea should I look for a general welding shop or an custom exhaust place? I can take the pipe off no problem and just take it in if they want. I've never really gone to an exhaust shop, I have no idea what a good one is here in the Milwaukee area.
