Not sure which part to change..exhaust ?s

[motorvated]

My exhaust is..well its loud. Ide like to mellow it out a little bit, especially while im cruising. I dont mind loud when im taking off..but I want to tone it down when im just cruising around town or on the highway. I run a resonated test pipe, non resonated mid pipe and a racing muffler. Most of the noise, is more like a drone when cruising. It comes from right under the seats, more so the the muffler. So I dont feel like I need to change the muffler. That leaves me with two things...The non resonated midpipe, and the resonated test pipe. Whats causing the drone? Im debating on changing the midpipe first. Either having a resonator welded into my midpipe, or buying a resonated midpipe. Ive got quoates for $115 to have a resonator welded into my midpipe(including the resonator) Or $128+ shipping for a racing beat resonated midpipe. What do you guys think? Would adding a resonator make a difference?
