check engine light from down pipe
i had my down pipe installed about two months ago and about two weeks later the check engine light came on. now when they installed it they told me it might come on because of my o2 sensor. has anybody else had this problem and if so what did u do to fix it

When and if you buy a staged kit it will not use the downstream 02 anymore.They make simulators to trick it into thinking it has one but i just bought the stage 2 and the pcm took care of it!!!
