Step 3: Install front mid-pipe into place.

Step 4: Install muffler, Place jack/stand under muffler for support.

Step 5: Utilizing the factory isolation mount now install the over-axle/tailpipe and tighten all clamps from front to rear.

Step 6: Your installation is now complete. It is recommended to re-tighten all exhaust components after 50-100 miles.
