not too noisy

Good morning all
my first muffler to order it was Flowmaster Super 44. I felt like I was the bad guy in the cart.
afterwards I imported the Flowmaster 50 series Delta flow. Let's say my mother-in-law calls for noise and scents of burnt out as always, and my wife has to take pills to calm herself down every Sunday when I start the Dodge.
can you help me find another model in 2.5 '' diameter?
I'm looking for a sound very close to the original to be able to pass for a very responsible 54 year old man.
