Has any one installed a resonator to kill the drone on a after market exhaust? No one with drone Problems? MBRP exhaust is what I have

Brandon R,

Drone is a wierd deal, some trucks have it the next dozen don't. We have an 18 inch overall resonator that does a good job reducing the drone, they are available in aluminized and 409 SS. Give us a call if you have any questions etc.

I installed one (it wasn't Mark's, but I do have his muffler) and it certainly killed the drone in the 1600-1900 rpm range. Matter of fact, with the flow through muffler and the resonator, I think the total noise level is quieter than OEM setup. The tone is deeper and richer, but quieter. And the EGTs are significantly lower.

Thanks for the replies, ordered the resonator, makes me feel better that someone has used one and they work!
