I am putting back my stock cats and getting rid of my DP..question do you need gaskets for both end of the joints or just the end going to the engine? Thanks!

You need both gaskets and they are different than those you use on a straight downpipe. Pick'em up from the dealer.

you don't need the gaskets. my friend passed smog without the gaskets.

Well sure you can pass smog without the gaskets, just like you can if the bolts aren't torqued to the right specs. If the question was whether cat pipe is put on with gaskets from the factory, the answer is yes.

Thanks guys for the information. Just to make everything neat and secure I have ordered both gaskets and 3 new bolts as well (about $24 total) from Toyota. It's gonna be a pain in the ass again..reinstalling the cats back.
