What cel are you getting and two is it a real cat or just a high flow "cat" test pipe?

Is the o2 sensor still plugged in? Deffinetly check the code.

yeah i got a 41 CEL code... do you guy think its the o2 sensor...
i thinks its a testpipe i bought of ebay

i had the same problem get adhesive and make sure the o2 sensor is in nice and tight with the vibrations from the backpressure it loosens your o2 sensor.

my o2 sensors is like welded on.. thats how strong its on there... i have tried taking it off but it looks like a C*NT 2 get off though

ebay test pipe??? you mean a straight pipe that replaces your cat? that's not a cat

so do you have a high flow cat or a straight pipe?

btw..."high flow" cats don't give you any power on a stock engine...turbo I could see though.



Either way, you have one o2 sensor and it's on the exhaust manifold and with that code you need a new o2 sensor...there should be some sorta check for that in haynes maybe...a resistance check that is.

I found this thread...mentions the check in haynes

A test pipe would definitely smell bad... you're spewing crap into the atmosphere like crazy without a proper cat! You should leave a cat on there, and only use the test pipe for racing. It's not that much of a power-adder that it's worth making you sick from the fumes (or killing the planet)

Replace the o2 sensor and see if it fixes the problem. It's not a bad thing to replace anyway, even if it's not the fix you need... with a code 41 though, it should fix it.

UMMM... well it says its a high flow cat, gives me more power at top end.... heres the addy for it

you wreckon its the O2 sensor...??? well its hard enough for me to buy one in australia... and damn the US ones dont work with my car from what i heard....

[NorcoAccord]

if thats a what you got it, its a test pipe, not an cat converter as for the 02 sensors get the part the number and if matches a us one i would think it would work, but who knows.

[bcjammerx]

do not...trust...ebay

put your cat back on...you did not gain any hp in the top end...go buy a new o2 sensor NOT FROM EBAY and don't cheap out on it either...otherwise you'll be replacing it in a year.

Seriously learn about this stuff before you do it, you will end up with a better longer lasting car. And ebay is not a parts store and is not reliable.

At least run stuff by us first and we'll save you a lot of time, money, and hassle...that's what this site is here for anyway...to support our fellow cb7tuners ;D

People need to stop buying stuff just because it's advertised as making more power. Seriously, would you believe that a plug-in chip that cost you $8.29 on eBay would give your car 45 more hp and 12 more mpg?

Test pipes are a waste of money and destroy the environment. We're not talking about 50-100 years down the road destruction here. We're already seeing the effects of greenhouse gases, and the damage is accelerating. Is roughly one horsepower worth spewing out 6 or 7 times the emissions? If you really feel it necessary, spend the money and buy a REAL high flow cat from Magnaflow or Vibrant.
