The reason I am leaning towards exhaust leak (at the headers/manifold) is that my truck just started leaking badly from the headers and it's a fairly similar noise....here is that noise...as you can tell MUCH more prominent....

What are the chances that BOTH of my cars get the same issue at the same time...


be careful...louder clip

99' Dakota R/T Exhaust Leak at driver's side header - Most likely gasket is just completely bad from header bolts working their way out....
