    I remember he had a buddy working his shop, and they where removing parts from old cars for scrappage, and the exhaust pipe was stuck to cata, so while empying tank of gasoline he used angle grinder to cut it of, and the sparks lit the tank that we emptied fuel into on fire. He panicked, and ran around looking for a fire exstinguiser my dad just got a blanket and turned the valv of while smoking his sig and threw the blanket on... all calm like.. Safty wasnt the first priority :P

    • @heygek2769
      @heygek2769 Před rokem

      X-ing an exhaust is really only done when you have 2 separate exhausts coming from different headers (usually a V engine) to even out the flow and pressure pulses on each side.
      Doing it all the way at the back of a single exhaust that just splits for mufflers seems like a lot of extra work for little benefit, it probably won't affect the sound all that much if it happens just before the tips, not to mention they don't have the space to make the bends and X the exhaust back there.

Just some thoughts to fine-tuning. Great work that you guys are doing.

    yes, as a tig pipe welder, fitup is key for a good weld in stainless. it is almost as important as having the metal clean.
    so for the people who want to know, clean the pipe more than you have cleaned anything before, then make shure you have a near perfect fitup, no sideways deviations and no gap, block off both sides of the pipe and purge it with argon or any other innert gas (make shure that the inlet tube and the exhaust hole in the caps are of a similar size or slightly smaller hole than tube and if there are more than one weld, make shure to tape up the other joints that you aren't welding to prevent oxygen from leaking into the pipe) and finally, take some time on scrap pieces to find the perfect settings for you to weld.

    you also have a section of pipe between two hard mounted locations, I would think you'd need another expansion joint somewhere in the middle of that nice long section that Isaiah fabbed up. I'd imagine it'd expand when hot and then crack a weld.

    • @heygek2769
      @heygek2769 Před rokem

      You mean from the resonator to the muffler? There are some significant bends in between.
      In long pipelines they actually use bends to give headroom for expansion. often like this: ____|¯|____
      That section of exhaust if it was straight should have a maximum of 1/2" (13mm) of expansion, probably more like 1/3" (8mm), since most heat is already lost in the front.
      Although i would agree its better safe than sorry. They could just expand the bolt holes of the resonator mount, so it can slide back and forth a bit.
