I just installed berk test pipes on my g35 and for some reason whenever I step on the gas the service engine soon light comes on and stays on... has anyone heard of this issue? I think it might be my o2 sensor telling my computer in my car that its getting to much exhaust fumes, but I'm not sure.

 

Its very normal to get a SES light with test pipes... you deleted the cats and now the computer doesn't know what to think. Your cars also probably running like crap..

You need a tune to get it running properly. If you have any questions about it shoot me a PM
