I say do a resonator delete along with a muffler delete and test that out first. If you have drone issues or don't like the sound, go from there. But, you will lose some backpressure due to no muffler or resonator so what I would do is delete the muffler and resonator, and put a nice free flow muffler or a resonated X-pipe in place of the resonator to dual tips.
