View Full Version : Where to order cats?

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 :p

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.

I replaced my cats last spring with the hi-flow variety from Jegs ($53 apiece).

I had them installed by a muffler shop, and they made new downtubes. My non-egr 90 SC isn't due to be re-inspected till May, so I won't know till then how emissions will go. But considering everything else I've done, if I fail I'll really have no way of knowing what the exact cause might be...
