My car has a 1978 Monaco 360 engine with a Mopar Performance Cam 4452761. It has original cast iron exhaust manifolds and dual 2.5" exhausts. The exhausts had glasspacks but I replaced them with baffle type mufflers. Why? Because despite liking the performance and behavior of the car, I don't like the muscle car sound. I like it in the right car but it just isn't right for my car. The swap out of the glasspacks was an attempt to quieten things down but hasn't done much.
So, although I know most of the questions here are about louder exhausts and power, what else can I do to the exhausts to lessen noise - especially at idle? Some things I've considered are: add an H pipe to even the sound out or add a crossflow type muffler ( like a Dynomax 17553 ) downstream of the existing mufflers, or add small second muffler to each pipe downstream of the existing mufflers.
Any suggestions will be appreciated. Thanks.
