    Since Milltek Exhaust ~ Back Popping/Pressure

    Hello Peeps, Since I got my nice new shiny exhaust fitted, I've noticed the beeza is back popping or has back pressure (whatever you wanna call it) within the exhaust occasionally when I let of the accelerator.... Is this bad, I heard that standard they do it too, but I don't recall mine...
