Long tubes with cats?

I want to get some long tubes still, but i will need to pass emmissions with cats...what have yall used as long tubes and cats together? What all has to be changed in the exhaust setup to get this done?
Thanks

I am not sure on this cause I don,t need to pass emissions so I junked my cat.
LTs will relocate your cats and I think that alone will make you not pass emissions. If you don,t have visual inspection and it is just a sniffer test you should be able to get by.
I am sure someone on the board has done this so I will let them tell you what needs to done.

FLP's have the interchangable cats to offroads. They still do relocate the cats but on my '94 it barely changed the passenger side location & the guy at the testing station didn't know & most wont know...
