heat.

performing this action.

washers from the kit, install the I-pipe assembly #25-

NOTE: Only snug all clamps at this time for adjusment
later.

Exhaust gas contains carbon monoxide, a deadly
invisible gas. Correct any leaks before driving!

Proper installation is the responsibility of the installer. Improper installation will void warranty and may
