I've always kept my resonators on.
I had the dod14m and the drone bugged me so I switched to the dod18m and it was ok for volume at full throttle but too quiet otherwise so I switched out the factory tips for 5"X12" and it deepened the tone but still too quiet, so I am now back to a dod14m it's deep, clean and pretty loud,lot's of drone and will be worse without the reso's so now after researching I pulled the plug and going to install the Cherry Bomb Extreme; more raw sounding,louder and NO gurgling like (******** in a tin can/ muffler delete without reso's) and smooth all the way through from idle to full throttle and a lot less drone. This is MY experience and other's will have a different view, good luck to ya, Bro.
