Bark too much for bite! Which Muffler?

Hi gang. When I recently bought my Cuda it had brand new 2 1/4" exhaust with Flowmaster 40's. It still had manifolds and it's original mild 273 with a mystery cam. It is my weekend cruiser and I love a loud Muscle Car and have had a beast Charger in the past, but this thing is way too loud for what it is. When warming it up in the garage it shakes the windows and pictures on the walls of the entire house. Living in a Southern California Suburb where the houses are 10' apart makes me cringe when I start it up before 9am, especially since I complain so much about the neighbor's kids behind us bumping extreme bass in their POS imports. The sound doesn't really fit the car and I would like to get a nice deep tone without all the loud, loping, in-your-face noise. Besides, the more stop light challenges I get, the more inclined I will be to totally turn this thing into a bolt-on-behemoth and loose my cruiser.

Any suggestions into a good muffler that is quiet when it should be?
