so i was wondering how hard it is to pass emission in oregon cuz i got an FC that i need to register and go through emissions. The guy i bought it from put an exhaust on it that looks to be about 2 1/2 with no muffler tips and it has one cat before the y pipe . Is this gonna be able to pass in oregon?

 

Yes.

But how is the question.

Try running it through DEQ how it is now, and let us know what the readings are if you fail [or if you pass ]

at worst.. You might have to borrow or buy a new cat, run it down to 1/8th tank and put two bottles of isoheet in the tank, and connect the output of the air pump to the cat ext. tube ["Split air pipe"]

Depending on your readings if you fail, is where we switch from using your cat or a different one. [The rest of the procedure is the same]

 

ok thanks im gonnna try to run through and see if i pass thanks for the info
