I failed smog, so i need to buy a new cat. Dont really know any good website to order from. I bought a brand new O2 sensor and i still failed, so it should the cat is no good. Timing was right on it. Car is 95 Civic hatchback with BAR'd B18c1, Comptech Icebox intake, DC 4-1 header, Skunk2 IM, stock exhaust. Replaced chipped ecu with stock p72 ecu and replaced O2 sensor with brand new one. Everything was good except i failed on the NOx.

 

there like $70 on ebay

 

when i needed one the cheapest i found was a high-flow from a local performance shop

i wouldnt buy from local shops, since they overcharge alot on their parts. Ebay will be the last resort for me

speaking from experience..

Dont waste your time on an aftermarket cat. I bought one from I4, and failed smog a few weeks later.

Find a good used OEM cat here on Honda-Tech. It will probably be about the same price as a new aftermarket one that it wont be 100% whether you'll pass or not.

the cat on right now is a magnaflow cat, which passed last year when i was still running the stock ecu. after a year of running the chipped ecu, the cat is no good and thats why i failed.

this is why you ruined your magnaflow cat, running rich from some bullshit chip, or directly failed emisisons from the chip

actually i bought the chipped ecu cause i wanted to tune my car, i needed a basemap and ecu to start with but never got the time to go tune my car. Im not going to ruin my virgin p72 ecu by chipping it, thats why i bought the p28 chipped ecu from a dude on this website.

 

Make sure you buy a Three Way Cat if you failed for Nox. Do you have an egr? if so make sure it works. what was your smog results?

It will be easier if i scan my results but i dont have a scanner. THe NO was over the gross polluter limits on the 15mph but it was under the limits on 25mph. Everything else was under the gross polluter limits but over the max allowed emissions
