BMW R NineT (2014-2020) K Speed Diablo Exhaust 

It’s tough to actually beat the tone of the stock.

@@martyn_g yea mine has the stock akro on it. I just removed the baffle. Got the scrambler model so the dual high exhaust looks nice too

You probably won't notice the bike be any faster or slower. Due to the short pipes and design of 2-2 exhaust, you'll have little back pressure. With little back pressure you'll notice the bike rev noticably faster, but you will also notice loss of low end torque. It's not a bad thing given this bike has tons of low torque to begin with, just something you'll notice due to the straight exhaust flow design. I did not tune my bike. At first the bike will run a little rough, but after a few miles riding, the stock ECU will learn the new air/exhaust flow and adjust accordingly. The bike will still run a little lean, but not at dangerous levels. In other words, tune is not required, but recommend if you want to benefit the most. A tune would probably be required if you modify the air box as well.

I take it you mean the exhaust flapper. I removed that ages ago (quite a popular mod for all year R NineT even with stock exhaust). Mine is a 2016

​@@StarManProduction do you have to install something to emulate that flapper? Or the bike will start without it

That is the rev limiter. Try revving all the way to red line, you’ll get it.

No stats on that.

It's a Harley Davidson brand headlight called Daymaker - Model: 67700430A. It is NOT plug and play, requires cutting and splicing. More information here www.ninetowners.com/threads/the-ninet-owners-bikes-photo-thread.49234/post-1101024

@@StarManProduction Wow thank you so much! Included the link and everything! I really appreciate it

Please reach out to K-Speed at k-speed.net/en/contact-us for pricing

I removed that entirely even before adding any aftermarket exhaust. No warning lights and ran the same. Just be warned, 2022+ R NineTs have a 3rd sensor and you will get an error light if you unplug that sensor.

@@StarManProduction Just to clarify this, I have a 2022 and removed my 3rd o2 sensor all together, no error lights, no issues. Been running a full Akra system like this for about 750 miles ;-)

@@5ub13 ah good to know

It just sounds so damn good. Any performance loss?

@@johnkwesi you know, some say low end torque loss due to lack of back pressure, but my butt dyno couldn't detect a difference.

it'll always pop unless you get a tune.

Hey, did you have three O2 sensors to deal with? I’m currently trying to install the Diablo on a 2021 pure

So in the video I did say it "should fit - but to check first". Apparently the 2021s have a 3rd sensor towards the rear that I did know about when making this video, in which there is no place in this exhaust. Yes it'll bolt right up, but there's no place for that 3rd sensor for this exhaust. If you disconnect the sensor or just zip tie it, you may get a warning light which would then cause your bike to go into Limp Mode

There may be a solution, find yourself a muffler shop and they can easily weld an O2 plug with threads in them to insert the sensor. Check this guy's thread out www.ninetowners.com/threads/flapper-delete-on-2021-and-full-exhaust-replacement.147906/

@@StarManProduction I’ll see what happens with the third sensor unplugged and let you know.

2014-2016 came standard with a rev counter and had a digital gear indicator in the middle. The 2017 and above Racer and R NineT (Standard edition with yellow forks) had different gauges where the Rev counter side has a small screen at the bottom for the gear indicator. The Pure, Scrambler, and Urban does not have that rev counter/gear indicator gauge cluster, but the wiring is there if you'd like to add it afterwards.

@@StarManProduction What other indicators does the 2014-2016 gauge cluster indicate? The 2017-current models have a gear indicator and fuel light on the gauge itself. Does the 2014-2016 have those indicators as well in the middle screen?

@@bhavinpatel2512 not much is on there. No fuel level, only a warning light that you're almost out of fuel, large gear indicator, milage/trip, clock, and if there's an error you may get a message (such as LAMP error when a bulb is out)

@@StarManProduction approximately how many miles does the fuel light come on? Not sure if there is a difference from the newer models. Also is there any indicators above the wording “nineT” or is it just a blank space?

@@bhavinpatel2512 depends how I ride it, sometimes at 90 sometimes at 120ish. Yes there are indicator lights in the gray space above NineT, in addition to Neutral light, an exclamation mark in case something's wrong, and high beams indicator.

there is not, believe me I've searched endlessly. Check out Pier City Customs Pro Rave exhaust.. beautiful looking system

@@StarManProduction what do you thing of a regular slip on exhaust for it, like akrapovic, Tc or Vance and Hines?.

@@tiestoXIV I've had Akropovic Catless headers and stock OEM Akropovic Twin Cans and sounded really good (just not as loud). I then had the catless headers and Two Brother slip on, but too high pitched and metallic sound (I didn't like it). Then I had the OEM catted headers with just the Two Brothers slip on Exhaust and sound was just right. loud but not deafening like the Diablo I'm this video

Hey, Ducatista, I got the same exhaust and unfortunately it won’t work with my 2021 r9t due to an additional O2 sensor, so I’m looking to sell it if you’re interested

@@Mr_Bibbles I’m interested in buying it! If you still have rhe diablo exhaust. I have a 2020 nine t

It won't work on a 2021 or newer R NineTs. It'll physically bolt on fine, but 2021+ R NineT has a 3rd sensor in the back, which this exhaust system does not have a place for. You'll get a check engine light.

@@StarManProduction damn! Sounds sooo good.. I wonder is there a great sounding equivalent available for my year?

They just released a new version for 21-23, it comes with 3 O2 sensors. They also still make a model for 14-20 that comes with 2 O2 sensors

No db killers are included. Furthermore, there are no holes to secure a dbkiller in it. K-Speed use to sell it with db-killers a long time ago but not anymore (I asked). It is really loud peaking at 110db and you'll want earplugs when riding.

@@StarManProduction I don't mind the 110, our test (not sure if standard everywhere) are at idle and at 2000 RPM. Do you have numbers on those? Would love to order for my bike. Thanks

No entirely too loud even with ear plugs

@@StarManProduction What did you replace it with?

@@pcohen85 I reverted back to my old Akrapovic Catless Headers with stock Twin Can Akrapovic exhaust with the silencers removed. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DvdBrs83UC0.html

@@StarManProduction thanks! I also have the dual Akrapovic cans without the silencers. I believe I will order the Akrapovic catless pipes also and run that setup for a while. It’s a shame the cans cover up so much of the rear wheel though!

Did you sell the exhaust?

I notice no difference.. before and after exhaust change I still get between 40-44mpg. But mine is a Euro 3 (2014-2016).... The Euro 4 and 2021s Euro 5 bikes may be different. I'm also not tuned which (though not required) is recommended with this type of set up

@@StarManProduction cool. Thx

The way I made it work was the two ends of the C-Clamp (that goes around the muffler) are under the triangle. The only thing that's above the triangle is a washer and nut. So, insert a washer on the screw first, then insert the screw from the bottom, into both holes of the C-Clamp, continue inserting the screw at the bottom of the triangle, as the screw comes out the top of the triangle, put another washer, and THEN put on the nut.

@@StarManProduction does it fit in the gap of the C clip. so the bolt then one half of the c clip then through the brace then the other half of the c clip.. . you see what I mean

@@MichaelPickles I see what you mean. I tried that, could not get it to work that way because the top c-clamp was way off from the hole of the triangle (you almost need to bend the top C clamp to.make it work that way). Even then, it would push the triangle and touch the other muffler, making it impossible to align the other c-clamp. I spent 2 days trying every possibly combination (even with the email K-Speed sent me with their pictures), but it just wouldn't work. The way I showed in the video is the only was I was able to make it work. The triangle is just a bit too wide for a smooth install.

k-speed.net/th/products/category/98470-BMW

Tried that, there was no way it fit that way because the triangle was touching the Mufflers therefore the holes in the bracket was off by at least an inch. And you can't push the mufflers out either.
