Have you ever heard a 235 with dual exhaust once the gas pedal was hammered? You may well find that it is a racket which you would like to silence quite a bit. Personally I find that noise irritating to the ear. I am not against dual exhaust, just the clattering racket with a 235.
I want the extra power but I would like a low growl rather than something too loud... it’s a 1954 235
Where is this "extra power" supposed to be coming from? With a cylinder head design from the 1920's, the only thing a dual exhaust system adds is another pipe and muffler to rust out, and a lot of extra expense. The constant ringing in my ears called tinnitus makes me wish I'd been kinder to my hearing a few decades ago.
I have invited several people to show me chassis dyno results of power they added by installing the popular dual carburetors and/or dual exhausts without making extensive internal engine modifications, and so far nobody has been able to document the alleged improvement they were looking for. Jerry

OP, I believe that Magnaflow and a few other manufacturers have sound bites on their web sites. How that translates accurately to your ears from a real life sample, I don't know. But, at least, it will give you an idea of sound along with the manufacturers description.
The loud deep tones comes from high compression, low compression engines just rattle the pipes. Any muffler that fits that's not straight through will be good. Hollow core mufflers ( Flow Master ) will rattle the pipes.
