That is great... yes I have a close friend that has only catless downpipes and he has the exact same set up as me except the massive cold air intake (from Project Gamma), which routes the filters behind the kidneys but other than that I dont have anything different than him engine wise and he has put 5k miles on his car with no issues. I do want to change the plugs and coils before I install the tune, you would agree with that, correct?
