Hey Tim, you skipped a couple things -- measure twice with micrometers, mark it with chalk, cut with a chainsaw and glue or paint to suit.

If you plan on sitting the mini sump behind the mini bow, I can't see where the durso will do much for anything. If you plan for it under a cabinet, then when the pipe is verticle and the durso is adjusted correctly (calibrated some call it), then it will be perfectly quiet and will not get air locked on you causing a mini flood.
