Hi everyone, I have a 1936 Chevy pickup w/235 engine; I installed headers & 30" Smittie mufflers, I don't like the sound they are producing, I want a growl w/a rumble ( deep mellow tone with the rapping. I'm now getting more of a Woof Woof sound. I used to have a friend in school that had a 49 Chevy & when he stepped on the gas the mufflers would rattle the windows. Anyone out there that can tell me the correct mufflers to get for the sound that I want? All help is greatly appreciated.
