How to remove servo assembly on header for m796/1100?

[thought]

hey guys...

i'm in the process of removing the headers on my m796 to have them ceramic coated but i've run into a bit of a snag...

anyone know how to take the servo for the flapper on the m796/1100?  i'm in the process right now, but i was following a manual for the 696 which doesnt have the info.  i'm guessing i'll have to take everything off in order to get it coated so i dont want to possibly mess something up if i just take a whack at it.

and since i'll be fitting a dp ecu afterwards... i wont need to refit the whole assembly right?

thanks in advance for any help on this

edit: or, perchance... does anyone know if i just dont have to remove the flapper assembly at all and can just send it over to be ceramic coated with the springs etc on?

Few questions bundled in there...

Is it just the headers you wanna have ceramic coated or the whole exhaust including the "Y" shaped midpipe?

So, about the servo motor under the seat:  
1) I dont remember how I took it off, but I do remember is was easy.  Just.... remove the bolts which retain it, unplug it from the wiring loom and disconnect the cable to the exhaust flapper-gate.  
2) DP ECU for a 796?  If this is designed to run with slip-on exhaust cans then it will NOT eliminate the need for the ECU to wanna hear back from the flapper gate's servo motor.  So yes you will need to refit the motor or else get yourself a Duc.EE to replace it.

Flapper assembly (within the "Y" shaped midpipe):
Unless you plan to cut out the section of midpipe which houses the flapper-gate and weld in a new plain piece of unflappered pipe then it isnt coming out (easily) and it certainly isnt going back in if you do get it out.  And furthermore if you have the midpipe ceramic coated with the flapper-gate still in place it will be a ceramic coated obstruction jammed in whichever position it happened to be at the time it was ceramic coated.  Never to flap again.  Not ideal IMO.

I think a little more research is needed on your part.   If you want to retain the stock headers, fit slip-on cans and have the exhaust system ceramic coated then I'd be replacing your stock 796 flapper-gated midpipe with an unflappered stock midpipe from a 696.  Its a direct swap.  You would also need Duc.EE to lie to the ECU.

This website has a very handy search function  .  I found these links which you might find useful:

thanks for the reply man

i've read most of those links already... i think where i got a bit confused is that i've seen some links where it said that the dp ecu removed the need for the servo.  i guess it meant that the full system ecu removed the need and the slip on ecu doesnt?

and yeah, i'm thinking i'm just going to skip the ceramic coating route till i find a 696 y pipe.  after looking at it again this morning, it's just not worth the trouble. haha

The slip on ECU still looks for the servo motor and will throw a code id it is not there, that is what the EE takes care of.

Thats right.  M1100 full system's DP ECU no longer needs any input from exhaust servo (for obvious reasons).  Slip-on kit's DP ECU continues to look for the exhaust servo.
