Cut away of a Dyno Max muffler #18381

Good to know a part number for a quiet muffler, I am going to have to try those Dyno max mufflers. I recently put flowmaster delta flow 50 series on a customer vehicle (non mopar) (ford 460) to see what they sound like. Flowmaster is an extremely high quality product that is made in USA but they are louder than I expected.

I would have liked a quieter muffler after I had a chance to drive the vehicle for a couple weeks
