6637 filter drone question
does anyone get this drone noise at idle? i ask cause i heard this weird noise coming from the front of the truck on the air filter side. it was kind of like a bop-bop-bop noise that would go away when i reved it up. does this sound like right or is there a different problem i should check for?

Did you just change to the 6637?
Any mods you do to the intake / exhaust will make it sound different. When I did my 6637 it was a low rumble sound I could hear and bothered me a bit but now I don't notice it. When I did the down pipe mod another annoying drown sound but now I'm use to it.

My truck makes lots of weird noises at idle and low RPM's sometimes... I think my downpipe clamp is rubbing on something.
My truck has had the 6637 since before I bought it so I havn't noticed anything odd from mine.
