I would like to run test pipe at the track without having to buy a new ecu. My friend told me that one of his other friends had a test pipe with cat material on the outside so that it would "fool" the o2 sensor into thinking everything is normal. This would allow for no CEL without changing ecu's. Does anyone know the name of the company that makes this test-pipe and does it work as advertised. thanks. if anyone else has any other suggestions that would be great.

When I asked AJ Racing, they told me that it all depends on the positioning of the o2 sensor bung. Can someone explain where I need to put the bung? If i can't find a ready made test pipe, I will just go to the muffler shop and have one made, but I need to know where to put the bung.

thanks for all of your help

sincerely,

Ken

thank you for the quick reply, have any of you guys used this test pipe? any gripes? are there other options as far as testpipes that are compliant with the OBD II?

 

well besides them being the wrong length and the cat material falling out a lot, oh and horrible customer service...

code 67 doesn't do a damned thing, if you wanta test pipe just remove the bulb, or wrap the O2 with tinfoil/wire tie it and replace every so often.

 

Test pipe compliant with OBDII... You're kidding... right?

Try www.testpipes.com they have test pipes available with cat material compressed in the o2 sensor bung. The CEL may still come on at random times. I have tried the Comptech hi-flow cat, and didn't have a CEL light for almost a year. Then it appeared one day, and never went away. I then bought an o2 simulator, had it wired in, and haven't had a CEL since.

Just get an o2 simulator to eliminate the CEL:

Or convert to obd1 and get a chiped ECU..!

I've had mine about 9 months with over 20K miles and no problems with it so far.
It's rather pricey for a test pipe, but it does the job.
