Test Pipe Check Engine Light Help
my friend has an 04 coupe. he had some kentix test pipes installed today and the test pipes had a place for the o2 sensors and we installed those but there was also a smaller hole drilled at the top of one of the test pipes. For what...im not sure but we had it welded over. Now after about 50 miles of driving his check engine light is on due to emissions. The computer says it could be the filler cap but its not that so im assuming it has to do with the test pipes..what is wrong..thanks

youz need these:
First off, for those who don't know, you need to buy TWO pairs of the non-foulers. One pair needs to be drilled out with a 1/2" drill bit (Most drills can't hold this bit, look at the pics of the drill I used... its over 30 years old). Once one set is drilled out, you take a drilled non-fouler and screw it onto the O2 sensor. Then take the NON-drilled one and screw it onto the DRILLED one. So the order goes, O2 sensor-->Drilled-->Non-drilled-->test pipe/cat. Once you go to do the drilling and everything, the order makes sense.
