Well, this year I just barely, and I mean barely, squeeked by on my emissions test. By that I mean if you had to score less than 100 on the 2 speed tests on Nox, I would have scored a 99.8
So before next year, I'm certain my cats will need to be replaced. Any recommendations? I need the 2" 3way cats. Also, anyone who has the 90 AOD (2 cats... No EGR) and has replaced their cats, I'd be interested in knowing what brand, supplier, and how it worked out as far as emissions and what special things needed to be done to locate them further down such as custom downtubes, header wrap, etc.
