I have the first gen F.I. exhaust, and I am also lowered 1" all around. I have never scraped my cans once.
And I have been in several places with crappy roads/approaches. As long as you take speed bumps and hills correctly (slowly, angled approach) you would have no problem. But Tony went one step further and made them even higher now.
Also, if you're worried about volume, Tony offers either 18" Resonated, 12" Resonated, or Non-Resonated CBE's to suit your taste.
