So i received my test pipe today and installed it. After about an hour of driving my check engine light came on. I have herd that its not a guarantee that your check engine light will not come on. Is this true?
Is there anything i can do about it?

This was my cel solution to my invidia testpipe.

Same thing happened to me btw and my friend as well.

go to napa and buy 1 pack of part # 730-2442
i had another pack to do my friends


drill 1 out like so



order from left to right - 02 sensor, drilled out one, undrilled one, test pipe


dont forget to reset your ecu after doing this.

have been driving like this for about 2500 miles no check engine light anymore.

thanks.... how did you come up with that idea?

I rly didnt some places sell anti defoulers for 30+ bucks and i looked at a few pix
And decided that i rather spend 4 bucks lmfao and make the same thing. All it does is move the 02 sensor further back so it doesnt pick up direct fumes.

i have a 06 with this test pipe and i put 3 anti foulers on there with steel wool inside of it and didnt drill it out and still recieve a light

Jeeze, 06+ s2k's must be picky!


To the OP, if you search you will find tons of threads where people use the anti-foulers to get rid of their CEL. It's cheap, and it works.

maybe try replacing the sensor itself? if you havnt tried that already.....

happened to me also, nonfouler solved my problem

call invidia they will give you a spacer for free that you don't need to drill out... Thats what they did for me when I called them and said my cel came on

i plan on buying flashpro, which just eliminates the 02 sensor
