I know I've seen a post before and tried searching but no luck in locating it again. anyways here's my problem. I just installed a Xerd race pipe on my 2004.5 auto coupe. all stock except for a 350Z tube. The "service engine soon" light came on after a day or two (maybe 50 to 100 miles after the install). I reset the light and a couple of days later it's back on (again somewhere between 50 to 100 miles). Is there a trick to get the light to stay off? I did the ECU reset at the time of the install.

 

Wow that's weird, ive had my XERD test pipes and Borla exhaust on for over a month and like 1500-2000 miles and no light!! Here is the fix, they are spark plug foulers that takes the O2 sensor out of the direct exhaust stream.
