I have a 06 rx8 and I just ordered a greddy sp elite exhaust system and I want to do a cat delete on it. The company I went to that's going to install the system told me that if I do a cat delete my check engine light is going to come on. My question, is there anything I can buy to prevent the check engine light from coming on. Thx

 

COB AP this is a $400 tool that will do lots of geat things I have one on my wish list. There is a few other options out their too but this will just mask the CEL so it won't show on your dash. Only thing I know of I have tryed all tricks I could find with the o2 and non work.
