Crossover Pipe



The exhaust manifold-to-crossover pipe connections are either of the ball type, donut type or flange type with gaskets. Remove the front pipe retaining nuts, space and heat riser, if equipped. Separate the front pipe from the converter using a torch (to heat the pipe to aid in removal), or if the pipe is be replaced you can cut the outside pipe carefully and remove it. Remove the air injection pipes, as required. Installation is the reverse of the removal, pay special attention to the fit and alignment of the system. Secure with new clamps.
