i bought a test pipe for my car and the check engine light has popped up is there any way i can eliminate that light?

 

bung for the O2 sensor on the test pipe...you have to back the sensor away from the exhaust flow or its going to throw that code everytime... you can create your own out of two sparkplug anti-foulers but you have to drill one out to allow the sensor a place to screw into.

there should be a DIY thread about it in the under the hood section of this site:

there it is


some test pipes have this issue addressed with a bung that is already welded in...if yours has this,. and you are still getting codes, you need to pull the code and make sure it not something somewhere else in the system

 

Thank you!!
