5 inch exhaust drone or rattle

RedRice589 · Apr 29, 2014

Wut drone are you guys having? Mine is quiet even towing... If I lay into it I can get a good one but it doesn't seem obnoxious. I would check all mounts and wise clearances on the pipe around the tranny and downpipe. Mine could easily spin around if I hadn't twisted it to avoid it.

Look at where the exhaust goes over the axle. It may be hitting the bottom of the bed. When I first put mine on I noticed it was hitting and had to do some adjusting.

I just had one installed on my truck and have no issues and the drone isn't bad at all.

Go to local muffler shop and have them throw on a big 'ol glass-pack or 2 depending on your noise tolerances. Cheap ' easy (just like I like my women).

I'm having a drone around 1300rpm. I will have to check and make sure it's not hitting the bottom of the bed to

I have a 5" w/ muffler and it's quiet at highway speeds.

When you tromp on it with the windows down it's pretty loud.

IMHO Ford has done a pretty good job of quieting these cabs down.

Off subject, but I didn't know you knew my buddy Barry Horne!

I just deleted mine and after the exhaust I can feel a rattle I have the gooseneck adapter thing under the bed though so I think its hitting !

i have a 4 inch w/ muffler and have that drone sound right at the same RPM, so im not sure if its just how they all are or if im indeed rubbing somewhere. Ill get under it this evening and check.

Mine wasn't hitting anything, I put the FTE resonator on it, and problem solved. It's so quiet it's crazy. Now I can hear the tires screeching when I stomp it on the floor. Before I couldn't hear anything BUT the exhaust.

Just installed my FTE Resonator the other night (17" model) and what an improvement! The drone was so bad when towing that I would drop a gear so I wouldn't blow my ear drums. Now I still have that sweet turbo whistle without that low rumble of the V8.
