    Here are the headers that I am making for the motor, These are stepped from 1 7/8 to 2" and are designed by computer to give the lengths etc to match the heads/cam.
    We will have two borla mufflers and the headers will be HPC coated

    They are some nice looking headers, How much would these go for?
    And a bit off the topic, I had an LS3 480hp engine, and its seems to be hitting
    a rev limiter at 5,500. Are you able to remove this from the cpu??

    5500 is a bit low, I think mine is set at 6200, it is adjustable via the ECU

    A set of pipes like that are around $1500, 5500rpm is very low, Yes it can be changed

    I assume you are talking about the factory ECU? If so I can change it

    In order to get into the computer I have to license it and that costs $150+ (as long as its not locked)
