What era of build number? There's been a few variations over the years.

im currently thinking of buying a new backdraft from vintage motorsport so it would be a 2014 model.

The muffler is 28" long and approx. 3" straight through. On current cars.

Do you two have heat shields on? I don't have the rattle so I imagine it's either the shield or a newer design.

I checked the shields on mine for tightness as well as the bracket because BD told me they sometimes crack. All fine. Even went as far as taking the shield off and driving the car. Rattles internal. No change with the shields on or off. Running a 408 small block.

I have BDR #471, no rattle on my end. Not sure how to expect rattle on a muffler...
