    Fits Like a Glove
    Great product. Better than O.E.M. Did not have to adjust anything with exhaust pipes to make this fit. I would suggest buying the gasket between Manifold and catalytic converter. Does not come with this kit. I rate the ease of installation low because it's very difficult to get to on my Cadillac.
