Would it be a good idea to replace em both at the same time? Reason is, the cheaper ones on ebay are 600 a set. I don't wanna dunk a Tom on cats if I'm gonna be replacing em with high flows on e85 at some point with long tubes. (Though long tubes are still on the table for me, still deciding between short/long) |

Have you confirmed if the factory cats are still on the car? Are there two per side? Although the B2S2 voltage is steady it's a bit high, so not sure how that would affect the outcome of an emissions test, although I'd suspect you'd be fine since you're not getting a P0430 code, so I'd consider replacing just the bad side.
As for the ebay cats, are they factory cats or a cheap aftermarket set? Just make sure they're 3-way cats or else you'll probably fail the E-test anyway as a 2-way doesn't do anything to reduce NOx.

The ebay cats are cheap aftermarket ones, they come as a set of both sides. 4 cats total, 2 per side. Not sure if they're 3 way or not, I didn't even know what the difference between 3 and 2 way was. And I'm not sure if the ebay cats are 3 or 2 way. These are one of the cats I was looking to get here I'm just looking for temp cats that'll hold off for a bit, until I can decide to get a header set up. Thanks for the info, I'll do a bit more research about 3 and 2 way cats. |
