I have factory short TORs and K&Ns, like the freak kit. There's a little rumble down low but when I roll on the throttle hard, they do roar a bit. Still nothing like the aftermarket pipes. I like the sound but after 7 years I'm looking for something else. Gonna try D&Ds but will probably get a set of Specialty Spares like Zmilin. Those are some sweet pipes.
