i heard that you can use the T1R 63mm test pipe without the o2 fouler and you wont throw a CEL... is this true? i have a MY01 and i was told by a my00 owner that a o2 sim was not needed for this setup..

anyone care to share their experience?

 

I say why not just use it since all you have to do is screw it in. Doesn't change anything, so I say put it in anyway and like that you'll know that the CEL won't come on at all.
