hi Neil, my welder guy didn't say anything about EMT or welding it......... I wondered about using that material ............but seems that it welded in just fine. I only ran that about 600 miles or so...........then went to a good OE type cat.

yes........anything galvanized gives off poisonous fumes when welded. is EMT galvanaized ? what I used that I think is EMT doesn't seem 'that' galvanaized.
