Two Brothers S1R Black Series Slip-On Exhaust Yamaha R1 / R1M / R1S

The Two Brothers S1R Black Series Exhaust takes the state-of-the-art S1R design to the dark side with black billet aluminum inlets, stealthy TBR badges and Two Brother's signature carbon fiber weave. The S1R produces that deep and throaty sound that TBR is known for thanks to their spiral-wound perforated core technology. The rubber lined natural finished aluminum muffler clamps feature an aggressive angular design and cutouts to reduce weight. The mid-pipe is constructed from .035” thick 304 stainless steel. After a few heat cycles the 304 steel turns a golden amber color, the hallmark of quality stainless. Of course an exhaust can't be all show and no go, that is why the S1R exhaust is track tested and dyno tuned to offer the best performance package.

Features:

  • Aerospace high-temp carbon fiber
  • Stamped spring-fit inlet
  • Eliminates catalytic converter 
  • Optional P1 and PX1 sound inserts available (sold separately)
  • Optional anodized bolts kits available (sold separately)
  • Made in USA

Note: Muffler image for reference only. Actual S1R Black Series muffler will vary slightly depending on your bike's make and model.

A real bang for the buck no doubt
The firts thing that caught me from this exhaust was the cat eliminator then after extensive Internet search and youtube videos I decided to go with this canned beast now my r1s sounds like a Mustang, totally love the looks and the sound is just unique, installing took my almost 2 hours and is not that hard if you have a little patience and the outcome will blow your mind

Before it sounded like a Prius now it sounds like a monster with a bullhorn
I bought my R1 and the cat and muffler were so quiet my buddy's R6 was the only thing I heard. I threw this on and wow what a difference. Watch the video and install was like an hour and a half taking off the OEM and Installing the two brothers. I love that it comes with the mid pipe when others do not. I was only reving it to about 7k as a reference. https://www.instagram.com/p/5NcTIvDdRV/

Amazing exhaust for the price.
This is an incredible exhaust for the price the performance gains from the weight loss are immediately noticeable. This thing is LOUD on an R1. I knew it was basically a straight pipe but this is annoy your neighbors loud. Get the P1X power tip if you plan on ridding off the track. The exhaust looks amazing sounds like a straight pipe muscle car and really improves performance. It wasn't hard to install but it wasn't easy either it took me and two friends about 2 hours to get everything in place and bolted in correctly. Get a servo buddy to replace the giant servo under the seat, with this exhaust you won't need it any more and it will save you a few more pounds.

Pros:
Not to hard to install
Sounds incredible
Huge weight reduction
Looks perfect on the R1 with the carbon fiber finish

Cons:
LOUD.... real loud

Looks Awesome
Really brings the sound of the bike out. The Black out version looks the best. Very easy to install, did not use the instruction it was so easy. It is the best looking Carbon Fiber Exhaust system.

Great buy!
I've always been a Yoshimura person. But, I have heard lots of good things about the TB's products. Well, bc of price and the cat elimination I decided to give TB's a try. My 2016 r1 went from sounding like a kitten to an absolute banshee with this new pipe system! Looks great! Sounds great! At the same time, along with this new exhaust system, I went ahead and added a PC-V, and BMC air filter, and a Yamaha servi buddy. The r1 is obviously fast from the factory, but now with these add ons it is a mad man!

Thanks Revzilla!

S1R Slip On
Great exhaust! Incredibly easy to install on my 2015 R1, only took roughly an hour. Comes with everything you need. This pipe is night and day compared to the stock pipe. Looks awesome with the low profile muffler, and sounds even better once you fire it up, that mean rumble you're looking for. A lot of bang for the your buck compared to other systems, highly recommend!

Luis H on May 4, 2017
With the muffler ending up right under the right foot peg, does this inhibit moving the foot pegs from being adjusted to different positions and does the muffler placement inhibit lean angle? Thanks
Russell W on Jul 13, 2017
BEST ANSWER: When most people move their rearsets, it's up and back which in that case it will not. No it will not affect your lean angle.
