I think it has a good look to it even though I am not really diggin the exhaust either. As for the seat, I am building a TCbros hardtail XS right now and I am using a spring seat, like most everyone it seems. What I am doing is fabbing a bracket coming off the center part of the backbone below the TCbros backbone mounts. Mount the front seat hinge point there so I can move my seat farther back. I can keep the rear of the seat more level, move it closer to the rear fender to close that gap a bit and not have to use ridiculously long seat springs. I like the clothespin style torsion springs better than coil springs and to me when they get over 4in, they started looking goofy.
