I havent heard of anyone running the Duncan or FMF exhaust on the 700s yet. I have a Duncan front bumper and the fit, finish and quality is top notch.
Im running the original Trinity full system(they dont have slip ons). It makes alot of power and alot of noise. It whistles when you let off the throttle. I had to machine a flange flat for it to seal. I believe this to be the best header design because the 2 primaries dont come to a y pipe till almost the frame vertical.
