I'f you are upgrading your exaust anyways, go with a new hi-flow cat, you dont want the old cat plugging up the work you did to open up your exaust
So I take I want the 3" 304 bolt in with cat vers the 3" bolt in with cat?
For the front power log if I get SS I don;t need to pick the option Ceramic coated
