Re: failed emissions test co help (coktavec)
Probly because ya dont have cats.
instead of getting true duals (I don't know what kind of exhaust you got), but you should consider getting a cat-back system. Then, you can change the cats once a yr. Have 2 sets. 1 pair as your stock ones, and 1 pair that you got in junk yard, and knocked out ALL the insides. This way, you only have to change your cats once a year, and have "true duals" for the rest of the year.
