[68 short step]

with all the pipes, in postion, I cut the tack welds at the flange, then fully welded all the pipes, then final welded them to the flange... once they were fully welded in, I clamped them using a big hose clamp, cut the primany tubes flush with each other, welded on the collector, then cut collector to length, and then welded on my 3" v-band...
