Title: Miltek turbo back exhaust
Post by: kodirl on October 18, 2019, 06:25:30 pm

Folks I am getting a miltek turbo back exhaust put onto my car tomorrow. It's a 200cell cat , non resonated type. My car has not been mapped yet and is totally standard.  I am aware I will have problems with exhaust cell light on dash. I won't be able to get the car mapped until two weeks time. Is this very bad for the car to drive it for two weeks like this before getting mapped?

You'll just get a P420 code for catalyst efficiency, will still drive the same just with EML light on.
