2. Remove the factory exhaust starting from the rear hangers and working toward the catalytic converter connection.
3. Position the new mid pipes at the catalytic converter outlets and test fit before tightening.

6. Tighten all clamps and hardware once alignment is confirmed.
7. Start the engine and check every connection for leaks before lowering the vehicle.
