Wondering if anyone can clear up some questions I have about my 2011, 6 cylinder XC90 catalytic converter. If you look at the attached PDF, the page 1 of 4 shows one catalytic converter and page 3 of 4 shows 2 exhaust manifolds with catalytic converter. Are there 3 catalytic converters in the XC 90 or is the first image for a different model? Thanks.
