We just happen to follow that trend (or actually set them in many cases that the EPA adopts later). What worries me is if they can/will lower them any lower knowing full well our older cars were designed to meet limits of the day, not modern ones.

As it sits now...big deal, you can definitely pass the testing- it is just that oxygen sensors don't work that well when they are 20 years old- you gotta get new ones. The problem is not clean tailpipes, but the rigid visual in this state.

I can see that I will have to try to get you to help me to pass when the time comes. I have not even looked into all the stuff I have to replace to pass visual since no C.A.R.B. approved stuff. I did buy a stock air cleaner so far and exhaust manifolds/cats from a 95 take off with 2K miles.
