    Welding exahust system ??\'s

    I've got to go the exhaust by March, so I'm going to get a new cat and new muffler. If the muffler and cat are stainless, do I need to set my welder up to weld stainless? What about aluminized tubing? And anything else I need to worry about?

    I don't know about stainless but you can MIG weld alumnized no problem.

    The exhaust system on my '75 is made from 316 stainless. A buddy TIG welded it all together. Made for some beautiful welds! The mufflers are Borla's, which are made from 304 stainless. We used clamps on the muffler, so it would be easier to remove the exhaust system, if required.

    The exhaust system should last longer than I do. [​IMG] [​IMG]

    Is the rest of the exhaust going to be stainless? If not, you will have to get a special wire (equivelant to 308s ss rod) to weld stainless to carbon steel. I would clamp the muffler &amp; cat to the exhaust to facilitate changing them out.
