I am looking for mufflers that I can run on my TDs that will eliminate the drone. I guess I am getting old, just wait it will happen to you to. Anyway I plan on running 3” to the axle and then go to 2.5” under the axle and mufflers at the bumper. I have read through the sticky and searched and can’t seem to get all the answers I am looking for. I saw many different mufflers but most were mounted under the seats and dumped (like mine now)and not much mention of interior noise just how great they sound. So what mufflers can I run at the bumper that will eliminate the drone, or is running them out the back the key to getting rid of the drone?

Run them out the back and use non-chambered style mufflers, something with a straight through perforated core surrounded by sound canceling material.

Are the Magnaflow 4" round bullets the non-chambered style?

Wait.... So are you cutting the once you have on now off or are you just going to add to the set up as is? Might want to try the Borla Pro XS

I have 3" duals with a xpipe, flowmaster super 44's. They are flanged at the back of that setup then drop to 2.5" and go under the axle thru a set of cheap summit glasspacks. It sounds awsome with little drone, at highway speed i can barely hear the exhaust over the suspension and howling 12 bolt.
