1. Inspect the original gasket for wear or damage and replace it if necessary.

2. Install the head pipe using original head pipe-to-cylinder head nuts. Do not tighten.

3. Carefully install the supplied heat shield material inside of the left-rear-fender closest to the head pipe.

4. Install the supplied steel hanger spacers into the rubber inserts in the exhaust hangers.  A light application of WD-40 to the spacer and the rubber inserts will make installation much smoother.
