Unfortunately, I recently bought a 06 evo9 MR with mods on it but before the person sold it to me, it wasn't smogged which I have to do. How many cats does our car have? The person gave me the cat, and stock downpipe. I just put the cat back on but i'm not sure if that's enough for smog check. Thanks in advance@

Did you come from a Subaru? My wrx had 3!

 

1 cat!

 

thank you guys! and no i didn't have a subby, i had/ still have a 2008 lexus is250 stickshift lol

 

OEM cat will get you to pass smog. Like others said, just one cat and it's right after the downpipe.
