Hello to everyone.....
I will try and keep this short. 2006 9-3 2.0T manual trans. I replaced the factory exhaust with a cat back replacement, now the check engine light is on. Was told to have car tuned for the new exhaust or live with it. The other option was to reinstall the factory system to clear the CEL. Any help with clearing the CEL would be great. (The code shows leak in emission)
Thanks
