    Nope, just some exhaust systems sound raspy/hollow due to their design.

    Listen to this sound clip of long tube headers and a true dual exhaust on the LS1:



    Don't tell me that doesn't sound awesome

    The engine block has nothing to do with the exhaust note.

    It is all in the systems design.

    Correct, but what I meant to say is that is not the reason for a raspy exhaust. Every engine has its sound, but a good exhaust is needed also.

    The reason the LSx sounds different from your typical small block is the firing order.
    It is different from your typical SBC.

    Whoever thought an engine block determined exhaust sound, needs a little introduction to internal combustion engines and their supporting systems IMO.

    like nhraFormula said, different metals produce different tones, and i agree. im not saying an aluminum block is the main reason for a raspy exhaust tone, but it dosent help either.

    I can post up a shot open headers from when I had the aluminum block and open with the iron.
    Give me a little time.

    They sound similiar. LSx firing order is the culprit.
