Hello Stovebolters, I'm running a 235 engine in my 1936 Chevy pickup & I installed a set of steel headers and a pair of 30" smittie mufflers & the sound is not what I wanted: What I have is a Whoop Whoop sound & what I want is a Rorrowww, a deep mellow tone sound, LOL, Can anyone tell me the correct mufflers to get for the sound that I want? I appreciate your advise. Thanks, Oldred
