High Flow Catalytic Converter
I just put a free flow catalytic converter few days ago now just not that long ago my check engine light came on. Could that be from the catalytic converter?

Re: High Flow Catalytic Converter (KGAccord)
it's likely that the free flow cat you got, unless it was like a carsound, was just a resonator or a test pipe, in which case, you'll get a CEL unless you somehow fool the second O2 sensor (if you have an OBDII 96-97 Accord). This can be done with a simulator or otherwise. Seen a lot of posts about this lately. And yes, orientation of a true cat does matter I believe.

Re: High Flow Catalytic Converter (carolinaACCORD)
the cel is likely for "low-efficiency cat". mine car's been throwing it for the last 2 years, it doesnt really hurt anything from what i can tell, it's just annoying. install an o2 simulator to get rid of the cel's.

so are the carsounds throwing cel's. ill be replacing the cat very soon on a 98 lx LEv AND IF I CAN GET AWAY WITH A HIGH FLOW without throwing cel's ever, then im all for it.

it keep the car's from going into close loop operation, it basically give you bad mileage.
the 2 sensor monitor the oxygen level in the exhaust gas, without the converter, you just keeping the earth

you properly dont want to get caught with a non-properly working cat converter(include rusted out cat, hollow out cat, free flow, test pipe and those non-carb eo'ed cat) in SoCal.

I have a 01 V6. Well, I took it the shop and the shop said that it's from the cat. I went to a local muffler shop to install the cat and they didn't install it properly. I just fixed it up, so far the check engine light is off. Hopefully it'll stay off. Yea, I have the second O2 sensor plugged in properly. Thanks for all your replies.

Re: (boonacka)
i dont think direction matters. i could be wrong but when i did my carsound i didnt pick, could have just gotten lucky.
if you got a universal you can get a spark plug de-fouler and have a local muffler shop weld it on there as an o2 bung and screw the o2 sensor in just like stock.
i had a carsound, stock cat and a testpipe. i like the testpipe the best. makes it raspier, but you can feel a bit more push.
good luck.

yah if you obd2 then you need the bungs in there.. they are there for a reason.. have your muffler shop put in a bung should be like 10-15 bucks tops..
if worst comes to worst and you think you've done it all and still have CEL, after your RESET THE ECU.. then pick up an o2 simulator
