    I was watching the video with Jay Leno's and his guest CEO of Dodge Tim Kuniskis was explaining the exhaust system was 5-1/2" straight through!

    Did I hear that correctly a 5-1/2" system ???

    Thank you !

    Yes. 5.5. Dual 2.75 inch exhaust pipes added together equals 5.5. It's an odd way to express the pipe size. They must teach you that in automobile marketing class in college.:rolleyes:

    "Odd" - no kidding
    A 5.5" diameter pipe has 4 times the flow capability as a 2.75" diameter pipe.

    Dual 2.75" system is how it should be stated. Or, if you absolutely must... Equivalent to a 3.89" exhaust system, but still just doesn't sit well. Nay - Dual 2.75" system.
