I have 50 series Flowmaster on my 66 and I have a pretty annoying drone at certain cruise RPMís. Iím assuming, right or wrong, that the drone is resonating from the body of the muffler as opposed to out the tail pipe.
If this is the case would the shield they offer help? Has anyone ever used them? Has anyone ever wrapped the mufflers with high temp wrap?
Or should I just bite the bullet and get new mufflers after only 300 miles?
