Cel for testpipe?

[way2slowtalon]

Hey guys quick question: On my 98 Rs, will I get a CEL or anything if I install a testpipe, with an 02 sensor fitting?

If so what can I do other than get a "real" cat?

More than likely yes you will get a cel with a test pipe. Search for o2 simulator or o2 bypass, to solve the problem.

my 97 has a full exhaust including header and downpipe, resonator in cats place and a 2.5 resonator back exhaust. when installing all this i even replaced my o2 sensor with a new one casue i broke the other one. i installed everything, reset the ecu and started her up. that was 6-7 months ago and i have no check engine light yet about not haveing a cat, and i know the light works cause ive gotten it for other things.

PM Paul (Velocita Paola) as he makes great working O2 Simulator boxes for our cars. So if you do get a CEL, you can throw one of those on there to get rid of it. I have a CEL for my EGR Blockoff so, to me, a CEL isn't a big deal to have on all the time haha.

Every since i put my high flow cat I have had a cel

just tie the o2 sensor under the car in a place that gets fresh air and no cel

so if i was to take my o2 sinsor out of the exhaust and just zip tie it to sumthing that gets air under the car it would be fine?

Maybe with a 4g63. You would probably get an out-of-range code if you did that with ours.

I guess its worth a try and see what happends but i think it will get a out-of-range code to.

[matt98eclipse]
