Healtech ESE - Flapper Valve Delete

I have purchased a Healtech ESE - so I can delete the Exhaust Flapper Valve action without getting codes etc.

If anybody has done this can they advise where I find the plug for the servo motor for the flapper valve?

Rather than go through all that trouble... take off the stock slip on, dremel the two tack welds holding the screws to the flapper, take the screws out, and then pop the flap out. Quick fix, no errors, servo is still connected.

Looks like a few folks over on ducati.ms believe you dont need an addon to prevent throwing codes.

I just removed the cable from the flap at the muffler and I got no code since 1500km

i also disconnected the cable from the flapper couple of hours ago. turned the key on, usual whirring of the flap motor, booting of the dash lights, started the bike and no errors. will ride it later during lunch break and see how it goes

Is the sound or reaction of the bike any different then before?

I read that the flapper valve is made to lower the noise at low RPMs. Which explains why it's loud at idle, quiet at low RPMs, and loud at high RPMs when more flow is needed. It shouldn't really affect performance noticeably...

Seems odd they would do this, and it wouldnt affect tuning at all....?

A lot of BMW cars have this. Search the 'golf tee mod' and it's very similar, except they use intake vacuum to actuate the valve instead of a motor.

no noticeable performance change, not even fuel efficiency

as for the sound, can't really tell when i'm riding the bike. perhaps when i let someone drive the bike past me... but then again, i've never had an off-bike sound experience so i wouldn't even know the difference

bottom line: nothing changes by just removing the cable. so i think i'll just reconnect it. makes me feel better that everything in the bike functions the way it was designed to.
