2. Remove "B" pillar support isolator .

3. Loosen band clamp at resonator .

4. Remove catalytic converter from resonator.

Important:

When replacement is required on any component of the exhaust system, it is important that original equipment parts be used for the following reasons:

Ensure proper alignment with other parts in the system

Provide acceptable exhaust noise levels

Does not change exhaust system back pressure that could affect emissions and performance

INSTALLATIONImportant:

This procedure covers installation of either the right OR left catalytic converter. Install the appropriate parts for the side that is being worked on.

1. Position catalytic converter to mounting position.

2. Connect resonator to converter. Do nottighten resonator band clamp at this time to permit alignment of all parts.

3. Loosely install a NEWV-Band clamp at exhaust manifold to converter pipe connection Catalytic Converter (Right Side Shown - Left Side Typical) .
