Mine hangs lower than the rest of the exhaust for some odd reason. Dunno why. My cousins pipe on his cobra hangs perfectly flush, so I'm not sure why mine does. It's not a big enough problem for me to fix though, since it doesn't really scrape anything. Then again I'm stock ride height also, so thats a factor.
EDIT: Forgot to add that I do like the pipe a lot though, minus the sagginess. Good quality, held up well for the year and a half its been on there.
