Castings are shot blasted, magnafluxed, cracks are
ground out, preheated to 550 deg, then we spray on a machinable
nickle that bonds to the parent material making it stonger than
the origianal material. After we are completed, we then machine
the surface flat so that when you put it back together you will
not have to use gaskets. This will insure no exhaust leaks..
We offer a 12 month repair warranty on all repairs
