1)  REMOVE THE OLD EXHAUST SYSTEM.  SAVE THE OLD EXHAUST GASKETS, SLEEVES, AND THE MANIFOLD STUDS AND NUTS FROM THE ORIGINAL FRONT PIPES.  

2)  INSTALL THE LEFT (#16541) AND RIGHT (#16542) MANIFOLD PIPES USING THE ORIGINAL GASKETS AND SLEEVES.  TIGHTEN ONLY ENOUGH TO HOLD IN PLACE.  NOTE:  FOR VEHICLES REQUIRING CATALYTIC CONVERTERS TO MEET EPA GUIDELINES, CONVERTER PART # 73-7774 OR EQUIVALENT SHOULD BE INSTALLED ON THE END OF THESE EXTENSION PIPES AND DIRECTLY IN FRONT OF THE MUFFLERS.  SEE DRAWING.  CONVERTERS ARE NOT INCLUDED IN THIS KIT.
