$30 is a good price. it is a silencer for an xlt/xcr. they aren't much louder than stock, just a little be more rumble when it is idling. one thing you will need to be concerned with is that your 98 (listed in your sig) will be the evolved chassis, that silencer is probably designed for the non-xtra12 wedge. it will still work, but you may have to "adjust" things to get it to fit correctly, mounting tabs, etc.
