Ok, Just got this bike earlier this week. Ive been reading, researching like a mad man. More hours than my wife thinks is necessary lol. So much info, I have myself confused. My M4 exhaust is supposed to arrive monday. Ive done header replacement on multiple bikes, but never on a bike that has exhaust valves and servos etc. I will do a flash with Dano in a few weeks when funds become available again. So..... in easy terms.... what do I need to do to change out the exhaust. Do i need to do this "servo buddy" thing? Thanks for the help, again ive been reading everything I can, Im trying to make sure Im prepared with everything I need come install time.

Since you have done headers before, I would suggest:

As you remove the OEM exhaust; you have to disconnect & removethe cables for the exhaust servo. The actuator (motor) that pulls the servo cables is mounted on the back of the engine in front of the shock; you should remove the actuator & cables (beware scraped fingers). Trace the electrical supply for the actuator and you will find it disconnects on the left hand side rear fairing.

And then you install the M4 and do not need the "servo buddy" thing....... You will need to flash the ECU, or you will get a FI code.



The other option is to use the servo buddy thing, and leave the actuator electrically plugged in and in place; and fool the ECU into thinking the exhaust servo is still working.

The M4 headers comes with 02 hole that you can put your sensor in, so that should be fine until you get a flash.
It also comes with a piece that you can put on the SET valve motor if you want, but most everyone just goes ahead and pulls the whole motor and cables on out. If you do this (pull it out) and you don't have a flash yet, it will throw a light. I don't know if the bike will run normal with this light on or not. It might go into limp mode.

Most of us did the headers and flash at the same time, that way we didn't have to worry about dash fault lights.

Also, You might want to go ahead and plug off the PAIR valve at the airbox or pull the valve completly out and install block-off plates. I believe this is to eliminate popping on decel.

So, If i don't want to take a chance of throwing codes I need the servo buddy. It will be a few weeks before I flash. How much do these cables, motors, actuator weigh? Maybe best to leave alone until after the flash?

My plan with all of this is to get everything together and then do it all at once. I'm currently stock piling pieces to the puzzle, then once I get everything I want to change I only have to tear it down once. I have an F model so it's even more worth it since apparently the fairings are a real pain to remove.

I get it. The riding season doesn't last for ever here in Colorado and the bike will be down for at least a week waiting on the flash. It will really suck to have that M4 just sitting in my garage taking up space.:D

That piece that comes with the M4 exhaust to put on the SET motor might keep it from throwing a code. I didn't use it so I'm not sure..
You could call M4 and see what they say. Maybe someone here might know as well...

After thinking about it. I guess I will ride the way it is now, then first sign of a bad weather stretch, send the ECM off. Then start tearing everything apart. Sounds like a pain, so I guess I will do it all at once and save the $60 bucks that the "servo buddy" costs.... any other suggestions still welcome though. I have a "bike night" at the local drag strip Sep 15. Need to be ready by then, Im almost 50yrs old and it will be my first time doing some "legal" racing... Gonna take both bikes :)

IMO Save your money and pass on the servo buddy, get the ECU to Dano.

Reag said the M4 comes with a little piece for the servo motor, my Arrow one was aluminum. You have to disconnect the servo cables from the stock exhaust to remove them, and up underneath the seat near shock (tight fit to get to) left side, is a little black box which is the servo motor (follow the cables) Detach it. You then attach the supplied piece to the center post of the motor there, it acts as a “stop”, stopping the rotation of the motor, fooling the ECU to think the exhaust butterfly is still there. I guess you have to reinstall the servo motor box and hide the cables somewhere.

I unplugged and removed my servo motor completely as had the ECU flashed, so didn’t have to deal with this. If you are going to flash the ECU, you can choose to leave in or remove the 02 sensor. And definitely (at least) plug the PAIR valve hose with a marble right side underside of airbox. Search for info on the Forum, many discussions with pics somewhere

I don’t think it will take a full week to send and receive from Dano. Keep us posted on your progress!

Will do! Ive decided to do the flash sooner than previously planned. While the bike is down and the ECU is getting flashed... it will give me time to remove all that servo crap and dial in the exhaust.

Thanks for the easy to understand info everyone, I bought this bike on a whim while I was actively looking for another MT-09. So I've been trying to digest a lot of new info quickly.

I sold my MT-09 to buy the GSXS. You made the right decision, the Suzuki is much more “substantial” and of higher quality.

I had a 2014 FZ-09 and loved it so much I was going to get the MT-09. Still love those bikes...fun as ****. But, after a couple days on this bike (and more miles on Suzuki than any other brand) I'm super happy, this bike is a keeper. I read a quote around here somewhere that rang true..... It was something like "you only hear people going from the FZ/MT-09 to the GSX-s1000, not the other way around". That rang true. I do love the low end torque of that CP3 though.;) Top end rush is no comparison though.

Did you mean “get the MT-10”? ‘Cause FZ-09 and MT-09 are the same bike! Look what you wrote above.

I do agree, the ‘09 has an incredible 3 cylinder motor, easy to wheelie, great fun, and I MUCH preferred the transmission gear ratios of the ‘09 over this GSXS. The 2 motors are night and day.

Anyways, back to installing your full M4 exhaust !

Yes. i meant what I wrote. I had FZ-09 and loved it. I had to sell it. Then when I was ready to get another naked, I was going to get another one (which is an upgraded, TC, ABS, adjustable suspension etc).The MT-10 is awesome but more than i wanted to spend. Yes the gear ratio is a little annoying on this bike but at 80mph even in 6th gear, she takes of like a rocket!

Perhaps I missed something said in this Thread, but my recollection is that the ECU Flasher (e.g. Dano's) can if asked to do so, remove the alarm feedback from the connected servo actuator/sensor.
Like all the sensor's, many reporting system's can be 'unchecked' by him.

Rapido1 and others who have used him say that he rings you, talks about what you want and and plan to do, before he does anything to your ECU.
There is nothing wrong with unchecking the sensor or exhaust servo at the flash, with those parts still working on the bike.

It's just if they fail to stay in Suzuki specification, you won't know (or care as you are saying that eventually you are wanting to remove them).
The one's that are unchecked don't stop the bike running, the essential alarms like oil pressure, TPS etc are never touched.
So you can flash it, then remove PAIR, Servo etc at your leisure with no alarms from them after the time of the flash or just leave them there in place too (but why?)

Rob, he initially was not going to be able to get the flash until several weeks after the header install. We were trying to talk him through what to expect without the flash.

I believe he's now decided to do both at the same time, which is a better solution.

Ok, the M4 system is in house. Ermax rear cowl fitted last night. Rad guard delivered. Levers should be in mailbox tonight as well as Saddleman seat. Block off plates ordered. just filled the tank, so I need to put on some miles by the weekend. Hopefully send the ECU on Monday morning. Besides a few more bits to add this winter.....I'm going to "leaveitstock". ;)

Work started yesterday. ECU in transit to Danos. Pair blocked. Started stock exhaust system tear down. The SET valve servo thingy is a B$#@*! Added a battery tender pigtail with USB, and mounted garage door opener.

Sounds like you are well on your way to creating the beast of your dreams. Looking forward to seeing pics and hearing how you like it once everything is in place.

Suzuki did indeed make the beast of my dreams. I’m just tweaking it to my tastes and style. I hope to be back to riding it again by mid next week.
