It does include an o2 extender and the o2 bung accepts wide band o2 sensors for tuning
Install took me an hour and 15 minutes from start to finish. I removed the top radiator mounting bolts which allowed me to slide the radiator off the bottom mount. I also loosened the bottom radiator bracket bolt so the bracket could move around which eased install. Starting at the head I installed the left most header tube first , hand tightening the bolts and moved across the bike. I had no issues putting any of them on. I used new exhaust gaskets but think you would be fine reusing the stock ones as they are very thick. I moved towards the back of the bike putting each pipe on without difficulty. I used a spring tool I had ( Akra should supply one but does not) I was impressed with the quality of bolts and they even supply matching bolts for the left passenger pegs so they match the ones you switch out to install the mounting bracket. The bracket is nice and light, unlike the previous generations boat anchor bracket that was used to hold the canister. Once the exhaust was on the bike , I moved from the back of the bike forward to tighten all the bolts. Many people do this backwards and start at the front of the bike which can give you alignment issues.
My highly calibrated bathroom scale weighed the stock exhaust at 16 lbs with the Akrapovic weighing in at 10.2 lbs with all the hardware for a savings of almost6 lbs
I wish the canister was a little shorter but overall am very happy with the looks, quality and the performance speaking of which lets get to the numbers
First is stock bike vs Akrapovic exhaust with stock ecu (no tuning): Nice gains across the range with no areas below the stock bike
See my separate page for intake testing
the exhaust can be purchased below with or without the flash and the flash can also be purchased by itself
2021 -26 MT09 /Tracer 9 GT/XSR900 ECU flash
This is the page to purchase the flash for :
2021 - 2026 MT09 (Base and SP)
2021-2026 Tracer GT 9 ( all models)
2022-26 XSR900
ON MODELS WITH CRUISE CONTROL: FOR THE CRUISE CONTROL TO WORK THE O2 SENSOR(S) MUST REMAIN PLUGGED IN. IT WILL BE DISABLED IN THE SOFTWARE BUT CAN STAY PLUGGED IN
You can also use these plugs to remove the o2 sensors and keep cruise control active * only needed if you want to remove the o2 sensor entirely for aesthetics *
ON ALL MODELS:
YOU WILL GET AN INITIAL CHECK ENGINE LIGHT AFTER THE FLASH. IT WILL CLEAR ON ITS OWN AFTER APPROX. 20 MILES AND A KEY CYCLE. AFTER IT CLEARS THE DIAGNOSTIC SYSTEM WILL FUNCTION AS NORMAL
To see information on this flash with testing results of different exhausts and intake set ups please see my 2021 MT09 specific page
2021 - 25 MT09 / Tracer GT/2022 XSR900 - FLASHED BY VCYCLENUT
(there is a link for the 24 specific content near the top of that page)
I have great flashes for all the exhausts currently out for this platform!
please fill out and send this form with your ecu . This is how you will tell me your modifications and what you want from the flash

The parameters I adjusted are:
:Adjustments to both the TPS and IAP fuel tables in all modes
:Adjustments to ignition timing tables removing all restrictions and optimizing them for best power at all rpm's and throttle postions
:Adjustments to throttle tables in modes 1-3, removing all restrictions in all gears with amore aggressive opening rate
:Adjustments to the engine braking tables
:Disable o2 sensor , can be removed or left in the exhaust ( on any model with factory cruise control, the o2 sensor must remain hooked up for the CC to work)
:Rev limiter raise 250
:Disable decel fuel cut
:Disable top speed limiter
:Turn on fans at 195
Note: Some companies are charging extra for a quick shifter fix. Claiming they can make adjustments to the stock quick shifter with the flash. This is a lie. The only software to flash this bike is woolich. There are no quick shifter settings in the software. After my flash you will find the quick shifter to be a bit smoother but that is just the result of proper fueling and nothing that should be charged extra for.
