which one would you say is better? also i don't understand the cat-back piping? it's the muffler and then the entire piping? or only half of it. i looked at the picture thai posted of it and i thought that cat-back meant the entire exhaust like the muffler and then full extension on the piping? but the pic only shows the muffler and then a little bit of piping? also does the remus piping extend all the way back? also thai, whos red legend coupe is that, that you posted? what did he use to lower it and what size rim is he running? and tires? that car sits exactly how i want mine too. thanks
