    Q:
    How should you replace a Catalytic Converter for the 2011 GMC Canyon? Posted by Natalee B.
    A:
    To replace a catalytic converter, you should raise the vehicle and support it securely on jackstands. Then, remove the bolts and detach the catalytic converter header pipe from the exhaust manifold. Remove the catalytic converter-to-muffler flange nuts and push the muffler back far enough for the studs to clear the converter flange. Finally, remove the catalytic converter and pipe assembly, clean the carbon deposits from the mounting flanges, and install the new catalytic converter.
