Starting a tread on CA Smog limits. I am hoping owners would put up pics of their results so we can figure out reasons and fixes for smog fails.
Car year, model, miles, etc.
I bought the car out of Colorado and I had to put the exhaust back to oem. Got cats from ebay with unknown number of miles and failed smog.![IMG_20231102_120118.jpg IMG_20231102_120118.jpg](https://www.nsxprime.com/data/attachments/135/135979-4569cbff8c042918ff6c446ed2b1263c.jpg)
Got a second pair of cats from a forum member and passed smog.

1995 MT with 60,000 miles. The forum member had indicated 104,000 miles on the cats that passed smog. The emission difference is striking.
