They are all good pipes (well constructed, good materials). MagnaFlow cats appear to me to be flatter than the Bassani or VRS so ground clearance might be a smidge better. For reference, my VRS cats are exactly the same distance from the garage floor as my stock H-pipe cats (i.e.--3.5") used to be.
Personally, I would like to see another delighted VRS pipe customer like me but you won't go wrong with any of the brands listed.
