Welded Exhaust Pipe

To piece together the rest of the exhaust we used an assortment of 6-inch mandrel bend 3-inch tubing (PN SUM-622005-SS) and 3-inch straight pipe (PN SUM-640130-1). We got a tailpipe expander from Summit as well, but it was too small for the 3-inch pipe. So we slit the tube (note the horizontal weld) to get them to slide inside each other. We prefer this method to butt-welding, since it’s less likely to break apart under the kind of use we’ll put the Jeep through.
