HOW TO Install Two Brothers exhaust 2015-21 Yamaha R1 DIY

This was my first exhaust install on a motorcycle, this was a fairly simple mod! You can easily do yours yourself as well. 👍

Can also unclip the o2 sensor on some bikes so you don’t have to worry about twisting the wires….might be harder to do on this bike

Pulled up next to a FZ09 yesterday and his crossplane 3 banger sounded BADA$$! I was on my KTM SMCR and he was in a hurry so didn't get the details on what pipe he was running. So now I'm exhaust shopping for my 17 R1S. The TBR S1R is a tad loud but your video put it to the top of my list. Easy install, no screwing with tuning, and good price. My main goals are that sweet crossplane sound and better throttle behavior (less choppy). Thanks

Sounds great.

Could you put an akrapovic slip on that same y pipe? instead of that two brothers?

[@badass1g]

I would guess they would be different. I could be wrong though.

Love the videos man! When will you have the video on removing the servo motor?

[@badass1g]

Hey buddy thanks! I have went 5k miles without touching the servo motor. Not sure if I’ll end up doing it or not? Waiting for a tune to be available for the 2020 so I can get some more power!

@@badass1g since you didn’t remove the servo motor, where did you relocate you two cables?

@@keithorlando6652 if you look close at the end of the video you can see where I zip tied it to that hose that goes to the little fluid tank.

Are you concerned there is no ecu flash available for the 2020+ models yet? I have the same bike, but running an AR DeCat GP1R exhaust. I don't push it hard, but hoping a tune comes soon.

[@badass1g]

I’m over 5,000 miles with this setup so far. I don’t even have the servo buddy installed. I certainly haven’t been taking it easy on the bike either. I am thinking maybe of getting a power commander for now and doing a dyno tune and an intake. Or I may just leave it as is since it’s doing well. I say enjoy your bike and let the computer do what it can to keep you safe. You could always check your AFR if you’re worried.

@@badass1g I threw mine on the dyno and it is running lean. Certainly not much performance gains without a tune. Power commander will only help up top from what I hear.

[@badass1g]

@@WideOpenThrottle1984 aww it’s good you checked then. I am at higher altitude and my tuners explained that I should be just fine. But the tune will help smooth out some flat spots and also give a little more power. It’s only $299 for the PC, that would atleast give you a bump in power and you’d know you aren’t running lean anymore. You can sell it if and when they finally do a flash one of these days lol.

How’s the car business

[@badass1g]

It’s on pause at the moment. I have some other investments that are outperforming. Trying to decide if I want to continue with cars or not.
