what does this mean?
 

Not legal for use on catalyst-equipped vehicles except for racing vehicles which may not be operated on a highway. Pre-catalyst vehicles must use original emission control devices. It is the responsibility of the customer to reinstall these devices on the vehicle.

It said that the cat must be relocated meaning its being altered from manufactureres specs. I know with the pacesetters the stock downpipe must be modified to accomodate the header. Maybe referring to that not sure?

so you need a dp beside stock i presume

it means that its not going to pass emissions inspection.

thank god my car is registard in michigan! they dont have emission inspectoins.

so how can it be 50state legal but not cali?

11. 50 States legal

thats a double standard right there. First you said it claims to be for track use only, and now you say it says 50 state legal. sorry but if its for track use only, then its not 50 state legal

the website says both
in the same webpage

then dont buy it... you cant have both, its one or the other.
