Hey guys, I'm restoring some early 80's Z's to be some good old reliable machines for my kids and neighbors to enjoy. Just trying to bring them back to good shape. The pipes I have on a few are either rotted or have holes blown in the sides of them. Can anyone recommend a good tried and true replacement for these Z's. I see the ones on EBay with the chrome guard but I am a little timid to order them until I know it's going to work. I'm sure they would work for the Z's in the 70's. Any input on some good pipe choices would be great. Thanks guys.
