How to Weld a High Performance Muffler

Hi I'm Doug. I work with twenty great guys in St. Louis at Doug Jenkins Custom Hot Rods, and we're going to do some work for you today on Expert Village. So now Dave's got on the welding helmet and he's going to go ahead and tack the front of the pipe in pretty carefully. He's feeling like the muffler is in the right spot and he wants to get the pipe firmed up in the right place there, before he goes ahead and welds the muffler in permanently. So this is kind of a nice car, it's a nice exhaust system. So he's going to do continuous welds on all the joints on this exhaust system. Now the benefit of that is good strength, it looks good, it seals perfectly, and it's kind of a level of craftsmanship deal here to do continuous welds on there. Dave's been doing exhaust work for, not continuously, he's mostly worked here at the hot rod shop for most of the last ten years, but Dave's done lots and lots of exhaust work before he came here. He does all of our exhaust since he's been here. He's really good at this. So you're watching a guy who really knows his stuff.
