Two Brothers S1R Black Series Slip-On Exhaust Triumph Street Triple / R 2013-2017
Two Brothers S1R Black Series Slip-On Exhaust Triumph Street Triple / R
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.
- Aerospace high-temp carbon fiber
- Stamped spring-fit inlet
- Optional P1 and PX1 sound inserts available (sold separately)
- Optional anodized bolts kits available (sold separately)
- Made in USA

Reviews & Questions
I will, most likely be purchasing the insert to tone the volume down. I commute on this bike all the time and don't want to be deaf in the next year. If I was just a weekend warrior looking to show off I'd totally just leave it as is, but I've resorted to wearing earplugs because I spend much more time on my bike than that.
I have a couple videos on Youtube posted for the exhaust. Please check out the riding video below and from there you can find the Installation video I made as well.
P.s. The picture is horrible sorry
This exhaust is EXTREMELY loud. I wear ear plugs and it still gives me a headache on the high way. I even installed the P1X tip and it has done nothing. I now have to try to recoup some money. I rode with it once and I removed it and put the old crash exhaust back on.
Besides how loud it is, it does sound and look nice. If you want a loud bike, then this is for you. It look me about 15 minutes to install.
