California vs federal cats for 1999 Taurus

Post by xrilander » Sun Feb 18, 2018 11:23 am

Hi there. I have a '99 with multiple hairline cracks in the y-pipe. Noisy as hell when cold, quiets down somewhat warmed up, no check engine light. Two Walker pipes available, federal, or CA emissions, $75 difference in price. My car has CA emissions. Question is, they are physically identical, can I put the federal version on my car, or will it set off the check engine light and fail emissions? Are the oxygen sensors they same?

Unfortunately Cali will check the cats to see if it is legal and they will fail you even if your car tests clean. That is why I am glad I live in Texas. The way my engine and exhaust is set up it would never pass. Bite the bullet and get the right one. Good luck.
