I agree with some of what Redlyr says. However, it is possible to pass CA smog tests with a set of LT if you also have a "catted" shorty X or H mid-pipe.Longtubes are illegal in CA and you will fail smog with them. An O/R H pipe will most likely make you fail too as they have not cats. Generally speaking any exhaust modification in CA will make you fail smog. Some stuff you can get away with if you know the test guy, but long tubes and O/R pipes generally are a no.
I do believe you are correct! My father has a set of the pacesetter LTs on his 01. With the pacesetters you wont have to undo the motor mounts. They are supposed to be easier to install than the macs.last i knew BBK didnt make LT's basically ur only choices are mac or pacesetter i believe (might be one or 2 more i havent heard of)
