I don't think either brand makes a cat back. Only axle backs. I've heard Fujitsubo Legalis R was one of the better exhausts, beating TRD by a couple hp, and really quiet. Not sure about the Power Getter, except the fact that it's pretty loud. Nobody has the C-One exhaust, though, but I'm sure it's just a rebadged exhaust from some other manufacturer (all their parts are; they're as bad as TRD with that kinda stuff :chuckles: ).
