I have a 04Z/m6

I recently remove the cats and put ( those tubes made by stillen) the ones that go after the manifolds into the exhaust.. but 3 days later my ses light came up...will I need someting to delete the light like o2 sims?

 

Sounds like you might have damaged one of the O2 sensors.

Cheers Amy -

It's a 555 timer IC - give Pulse to tell computer every thing is fine..

 

Go to auto zone first they will tell you what code your computer threw. It's free! My 34/mt did the same thing. After reset it never came vback on.

 

ive had the light a few days after i installed my kinetix pipes too. the SES light has been on ever since too. I cant come up with any ideas.
