Why not just get a resonated X-pipe or even non resonated with HFC? More power, more noise and no drone... per people who have done it.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
