whats the difference between catted and off-road x-pipes.....and is slp a good exhaust kit, i am looking at the loadmouth kit.

 

and would the x-pipes serve the same purpose as a adapter kit for the v6

 

Xpipe doesnt serve as a replacment as the adapter kit they have. Catted XPipes is a midpipe in an X configuration that has cats on them for emission purposes. Off-road X pipe is an xpipe WITHOUT cats. They wont pass emissions if your area requires them, and they are illegal. They arent seen and even though you CAN get a ticket for them, you probably wont.
