Re: piping into exhaust?
Okay... well..
This so called EGR, does it help the engine at all??
I don't really think I'd want exauhst going back into my engine if I had the choice...

Re: piping into exhaust?
Someone else posted that our cars don't have EGR. I think I'm going to crawl around tomorrow and see if I have this tube you are talking about.
Anyway, if it is EGR it's ok. An EGR system sends exhaust gas back into the intake as a replacement for fresh air. This is only under certain circumstances (which I forget). The purpose in this case is to allow additional gas to flow through the combustion chamber to cool it down which reduces the NOx emissions.
