If you're not on the highway much, drone shouldn't be a big deal and cheaper exhaust might suite you. One 20 min ride with mufflers that droned, right around 2k (highway speed) convinced me Borlas are worth it! I have the touring catback system which has the resonators. I also have over axle pipes w/o resonators that makes the system louder but still no drone. Custom isn't a bad idea. Shop around local shops and see what they can do.
