I dont know what u mean by y-pipe but depending on where youre describing you may have either a plugged catalytic converter or a fuel mixture problem...or even both.

I am referring to the point at which the two pipes from each individual manifold intersect to create one exhaust pipe creating what appears to be a Y.Thanks for the input and you are on the money,the problem was in the fuel mixture.running great now thanks again.
