Re: After changing exhaust SES light came on??
That seems odd. I went from cat/muffler to a straight pipe and I didn't get the light. But I'm guessing it's just because the computer isn't used to the lessening of the backpressure. Have you unhooked the battery for a while, rehooked it and went driving? Maybe a simple reset? Or you could just check the codes and see what it says.
