I have recently installed a Trust(Greddy SP1) Muffler and a Straight pipe(test pipe) along with my Y pipe I have installed about 1 year ago. Right now I am running my (2.5") Y pipe-(2.5") straight pipe- "2 1/4")stock catback to my (2.5")Trust muffler. My question is have any of you guys noticed throwing a 0302 Code (EGR insufficient or excessive flow detected). I am assuming thats because of the extra flow with the newer free flowing exhaust. My question is with this code will it affect the cars performance at all. I have heard that it will not affect it but I want to check with you guys. Any help/input is greatly appreciated.

BTW I will be getting my 2.5" resonated cat back installed in a week or two depending on when I have time to.

 

Bump....Please help...

I got an 0302 code a month after installing a y-pipe. I think the events are unrelated. Try cleaning out the area where the egr system connects near the throttle body. From some of the threads that I have read here, that area can get very dirty causing the cel.
