    Irrespective of any technical considerations, I must "like" post #39 simply because it contains a hand drawing.

    It has been said that "you can't beat something with nothing." TX, this is something. (Also, it appears you can handle a pencil, which earns extra credit.)

    Sure, but was it a Pentel? With HB lead? Looks like it could have been 2H. I wonder if he has a scum bag.

    Scum bags are always welcome. :)

    I could understand baffling, but individual chambers could cause a back pressure differance affecting performance.

    What would be the correct way to accomplish:

    1. Max Power
    2. Best Exhaust Sound (i.e., Loud!)
    3. Correct Cosmetic Appearance

    What size do the chambers need to be? All equal in size? Or just one big hollow log-manifold? The downside is that it will not sound nearly as good as a multi-chambered exhaust.

    The race team at Hutter Performance is feverishly working on this right now.

    As the customer, what are YOUR requirements for the outcome? This will drive the "...correct way to accomplish..." actions. The three choices you have here are largely in conflict.

    Understood. It is a compromise in design to come up with the best overall approach.

    But this is the goal:
    1. Max Power
    2. Best Exhaust Sound (i.e., Loud!)
    3. Correct Cosmetic Appearance

    Here is a LS376/495, straight short stack:


    And here is an LC9 327, log manifold, non-chambered:

    Glass pack and a cuttout might be a choice.
