2009 Alloy Metallic Gt500
Looks like the same setup as mine. 2.6” pulley and metco aux idler. You’d have to measure the pulley to be 100% sure. I don’t know about CA smog but here in NV you can still pass tuned as long as all monitors are set and no CEL’s present. In my mind, as long as the cats are still present you should pass. Unless they do a visual and actually know what they’re looking at. The car is most certainly tuned, I can’t imagine it would be running right with those mods on the stock tune.
