Assuming it is not just in the receive line, a bandpass filter may help you keep peace with any neighbors who are on the same band and others in the contest - as it will cut down on any extra "crud" your transmitter produces.    It even works with "clean" transmitters.

If you have a second receiver, then a bandpass filter could be helpful if you are trying to receive on a different band than you are transmitting on. For example, you are running on 40 meters and tuning for multipliers on 20m. If you had interference on 20m from your transmitted signal on 40, a bandpass filter could make a big difference in being able to hear 20m as you transmit on 40m.
