posted by someone claiming to be andrew on Sun Feb 25 13:25 CST 2001 [RELATED]

I have recentlyinstalled the atr 2.5 inch downpipe and have a had a 443 code displayed (inefficient cat) Has anyone else installed this pipe and exsperienced similiar. Any way to solve this easly, like programming the ecu not to read cat.

Another though, you do have a cat in right? Or did you go for straight pipes?

I installed the cat and DP and the only problem I have ever had was a slow O2. Not sure it matter but I am also running an aftermarket ecu. 443, I have never seen that code. You may want to contact ATR. Sorry I was not more help,

Charles I do have the cat installed and yes I am displaying the slow 02 reading on the front sensor. Any cure.
