Default Exhaust flapper valve

I installed the Termi exhaust slipon for my M1100 EVO but I've been reading that the Duc.EE is a good addition to this. Can anyone explain the benefits of dropped $130 just to remove a servo and a bit of cables? Is there any reason I should do this?

Just disconnect the cable at the flapper valve. The valve defaults to the open position. This way the ECU thinks everything is operating as normal with out muting the exhaust note. The DUC.EE is good if you wish to remove the motor & cable assembly.

+1 on just disconnecting the cable. The duc.ee is $150 for a small weight savings basically. Only other reason to install the duc.ee would be if you get your hands on a 696 midpipe.

Doesn't the TERMI ECU disable the flapper so you can completely remove everything?

I don't know what I did wrong... But disconnecting the cable at the flapper side would flag a check engine lights still. I have the termi slip on with the ecu installed. This is a 2012 1100 EVO.

Hi Scott. Yeah that is where I disconnected it. The actual cable. The check engine lights came on for the ride. Reconnected and it went away. U think the servo motor actually knows it is disconnected by less resistance or travel?

I had my ECU flashed with the DP map and to ignore oxygen senders and exhaust servo. I removed the servo from under the seat but left the cable attached in case I need to re-install the stock pipe. Never saw a check engine light. 2013 M1100.

Only thing I can think of is that the cable got snagged on something so it wasn't able to cycle fully/properly. I've had my cable disconnected for like 1k miles and never had a problem.
