Cutting the pipe doesn't allow the exhaust gases to recycle threw the engine...hence canceling out the EGR...Also welding a flange onto the new headers will not work either according to JBrady the designer of the S&S Headers...I had already thought of that....
However that is interesting that just by cutting the exhaust flange pipe and capping then installing the new headers you didn't get a bad read or idle....Wow, I would have thought different....What is the point of the deletion kit if that is all that needs to be done? Something is a miss hear.....
Still would love to know how to have the headers and EGR work together .......there has got to be a way... Really the only way I can see the EGR working is by re-welding that sensor that comes off the stock exhaust manifold and relocating it somewhere on the exhaust system or on the S&S Headers.. ANYONE??????
