    Welds OK
    Would be great if ends were like 1/2” longer so no welding would be needed could jhst clamp on. Could even sell clamps with it… but it welds alright. I had 4” od “aluminzed steel” and it slid nicely inside of cats opening making much easier to weld than if it was a butt joint. This was welded with a 110v lincoln flux welder and .035 standard everyday flux wire. Low/medium volts and medium/low wire speed. 90% of the weld is on the tube that slid in the cat and slightly just bring weld up to grab the edge of the cat and then back onto the tube. No idea how long before it rusts, but awell will pass emissions and can clamp old cutout exhaust back in its place. Use good big butt clamps (unless you have flaring tool) and some exhaust tape between clamps.
