Personally I've owned only the BBK Longtubes. I loved 'em, great clearance and great fit. Never leaked. Only complaint I had was that their polished coating starts to rust through in spots and this was on a car that was garage kept and only driven about 5000 miles per year. Now I am having them sent to Jet Hot along with my off road BBK H-pipe to be stripped recoated and polished. Buy the non polished and get the Jet Hot brand coating.
