    I remember something about that! Can't remember what the story was. Probably boils down to money (like everything).

    Fixed
    Looks bimodal. I suppose you've got one of those BTC remotes for it?

    Yep. The Fiammenghi exhaust comes with it own valve controller but the instructions are written by an Italian so are bloody complicated. Needs mucking around and sticking wires into the Engine ECU. I decided it was all to hard so bought a Forza controller as well, US made, clear instructions, basically plugs into the valve solenoid so seems very easy to fit.

    Didn't think the ECU would need to know what's going on that far downstream

    The signal for the open/close valve position originates in the engine ECU and is dependent on throttle position/RPM, so Fabio’s solution is to hook in a bypass module at that point. The Forza solution is downstream and interrupts the signal when it gets to the solenoid level. Seems much simpler, but if it doesn’t work I’ll use Fabio’s

    So the 575 has a bimodal exhaust as standard?

    Are those stock mufflers as heavy as they look Greg ?, I imagine you’ll save a kilo or two with the new set up
