Header & X pipe install question
I just installed a set of Kooks headers and X pipes with high flow cats in them. I have an 09 m6 npp and everything went well for me I could not believe how easy they went on !!. But, after driving it for about 60 miles I had the check engine light come on so I went and had it checked and it states that I have two codes. P0430 which is catalyst efficiency low-bank two and P0420 catalyst efficiency low- bank one. Question is, is this normal after header xpipe install and is that something that can get tuned out. I have an appt. next week to get it tuned. Also, will this hurt my engine to continue to drive it for the next week ? Thanks for the help !!
