Oh for the love of what ever you believe in, Its not just a Cat Back. Read the info please, enough is enough the complete exhaust was replaced, the Y-pipe is gone, the cat has been changed, the pipe size has been increased, the muffler has been changed plus the routing has been changed.
Has anyone else on this board done a testing regiment like this? Modify then test, do the next mod then test? Not that I have seen. I have seen I did this and this and this and this and then I tested. How do you know exactly which mod did what. If someone else has done a mod by mod test series please tell me so I can look at it and compare results.
