Cat Positioning....
I notice that certain HFC's have the cats in the same place as OEM (a la Fabspeed) and some have them further back in the x-pipe (akra). What, if anything, is affected by cat placement? Are you less likely to throw a code w/ the cats closer to the motor? how is performance affected, sound, etc?
