I'm seriously considering these. It's just too bad they didn't extend the driver side pipe to just before the secondary cats to get rid of those nasty stock bends and kinds.
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."
