Both of my " Batwing" manifolds are cracked. Seeing that they are as scarce as spotting Big Foot what are the options that don't require getting a second mortgage to buy?

Even when you could still get them (I bought the set that's on there now in 2004) the originals were about 377 a side, so 600+ for the aftermarket 2 piece is not bad. I'd like to see if the Merc dry joint system could be adapted to the OMC exhaust Y pipe because it is a superior design in terms of avoiding leaks into the water passage.
