    Balanced has a connecting tube after cats, before mid mufflers to create an h-pipe or "balanced" exhaust system. Unbalanced maintains full dual exhaust front to rear.

    There are two types of drone. The 1800 rpm one can be fixed with j-pipes, some folks have had good results with Corsa.
    The other drone is the AFM changeover and that can only be fixed by turning it off. Only 1.5 mpg loss if you do.
    Hope this helps.

    You can push the envelope, but it's still stationery
