It's funny how poeple NEVER mention they're exhaust need to be adjusted, and only RAVE about how cool it it. Thanks for the TRUE update. I had a similar experience with my Riss unit.
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."
