Thanks for the advice. I think the truck has a nice deep sound, its not as snappy and "put put put" sounding as mine and I like a little of the raspy/growl sound when he steps on it real quickly and short duration. The previous owner told me my 350 SBC has an RV cam so it lopes a bit more. Any implications this may have on my idea of going with the 22" Brockmans, 2" diameter pipe and straight through pencil tips? I'm thinking of putting the glasspacks between the A and B pillar lengthwise.
