I have read a whooooooooooooooooooolllleeeeeeee bunch of threads and haven't really seen this question addressed. I kind of have a unique situation. I am from CA and that is where I bought my 04 Z71 5.3. CA has strict emissions laws and doesn't leave much room from messing around as far as exhaust or any performance upgrades for that matter.
I now live in MI where they have no emissions laws of any kind.
So the question is do I need to change my converters (CA Truck) or are they the same regardless of the state it was meant to be sold in? I'm pretty sure I need some kind of converters for the back pressure
?
I want to do headers and a cat back conversion but I'm not sure if I should just go for the whole header back (headers, cat, exhaust).
Any help would be greatly appreciated
