You get what you pay for
I called around to get pricing on having 2 pipes with minor bends welded into a y-pipe. Most places quoted me around $150, but I went with Andy's and paid their price of almost $200 anyway because I had work done there before and the bends are smooth and welds are clean.
They are pretty quick with their work if they aren't too busy.
I can't say how they are with anything outside of exhaust work.
