the silencer is a 4 stroke silencer and should not be used on a 2 stroke, even if it would fit, the pipe I.D. is prolly double that of a 2 stroke pipe.
the nerf bars are prolly too big as they are and may interfere with the front tires
although they may be able to be modded to fit.
i used ltz400 nerfs, but had to cut 5 inches out and reweld them.
unless the nerfs are very cheap, and your modding/welding skills sharp ?.......i'd just look for blaster nerfs.
