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

The Two Brothers S1R Slip-On Exhaust represents a step into the future for TBR. The S1R exhaust features a carbon fiber sleeve highlighted by a natural aluminum outlet and stamped, spring-mounted inlet for the ultimate durability. Like most TBR mufflers, the end cap of the S1R exhaust is constructed of magnesium and features a non-stick teflon coating. However, that is where the similarities end.

The aggressive design of the end cap is reminiscent of the modern jet engine making this exhaust move at mach 1 speeds while standing still. The carbon fiber sleeve of the S1R exhaust system is made of a 33 million modulus rated carbon fiber that is impregnated with high temperature resin, under very tight tolerances. Thirty-three million modulus rated carbon fiber can be considered the Goldilocks of carbon fiber , it has strong structural properties without being overly stiff and brittle, making it just right.

The sound produced by the S1R is deep and throaty thanks to its 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.

  • Fully-serviceable in the event of damage, routine maintenance or the occasional repack

  • Stamped spring-fit inlet
  • Eliminates catalytic converter 
  • Optional P1 and PX1 sound inserts available (sold separately)

Couldn't beat the price Revzilla had. Had to buy it.
Zach D on Sep 8, 2016
the built in link pipe sealed the deal, since the bike is a new design there aren't many options but all my liter street riding buddies swear by Two brother and it's not an arm and a leg of the other guys but still a great sound and performance!

I love this exhaust! It has a great deep tone to it and it is really loud with the cat delete. I always get head turns and positive comments when I go places. 2015 YZF-R1

I've always been a fan of Two Brothers sounds. The exhaust, though technically a slip-on, eliminates the cat...allowing a more pure sound. Plus the performance.

For the price as other exhausts are going for, this is the most bang for your buck. It tucks away nice and neat almost under the bike and it looks great too. Two bros has been making awesome sounding and looking exhausts for a long time and I would recommend them without a doubt.

Does it need the cat elimitaro or it comes with it ?
A shopper on Apr 2, 2017
BEST ANSWER: Mine came with a Y-pipe to eliminate the cat. The y-pipe has two sockets for the oxygen sensors. It's a VERY tight fit so good luck
Does this come with the midpipe?
A shopper on Jan 30, 2017
BEST ANSWER: Yes Bro, it includes the midpipe. It sounds great. I would recommend you to add the P1X Power tip because the exhaust it's very loud...
