Finally getting started now that it is warmer

I found a 1.5 pipe can almost be shaped into a rectangle that will fit, but alas it was just a tad too small, I went with 1 3/4 pipes and made them squarish in a vise and still had a little overlap at the flange, perhaps some AB epoxy to smooth out the step...
<<<<< CORRECTION >>>>>>>> mine were Aarons intake flanges...my bad. But the intake ports are larger than the exhaust ports on a slant....
