Two Brothers S1R Slip-On Exhaust Triumph Daytona 675 / 675R

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.

So Far So Good I've had this exhaust installed now for about 2 months. It sounds great! As far as the installation went... Taking the old system off was about 80% of the total time for the swap. In all it took about 2.5 hours. Once the old system was off it was literally 30 minutes and the new exhaust was installed. Another nice feature was that the kit comes with a dummy switch for the old servo motor that was removed (I think the dummy switches are $55). Back to the sound... The bike sounds awesome now. I definitely notice a lot more attention when riding around now. I also notice a lot of unpleased looks as well but they can be mad I guess. I would highly recommend this product. June 27, 2016
Two Brothers never disappoints. It was either this or the Arrow slip on. I went with TB because it had more of the tone I was looking for while still maintaining the signature Triumph engine whine. Installation was easy and it looks amazing on the bike. I love the sound. March 15, 2016
Excellent Addition Just a great product all the way around. I investigated other more expensive exhaust options, but couldn't resist coming back to this one. For the price, it absolutely can't be beat. I had the dealer install it, so they could tune it after, so I can't speak to the ease of install. Performance is remarkable. The bike definitely feels a little zippier and quite a bit lighter. The exhaust has a beautiful sound, too. It maintains that distinctive Triumph whine, but bolsters it with a lot of throaty grit in the low and mid sound ranges. It is loud, but it's a good safety feature. People will definitely hear you coming. I couldn't ask for anything more on the finish. The carbon fiber on the exhaust perfectly matches the carbon fiber detailing on the front fairings. Really a terrific product. January 31, 2016
excellent quality and easy to install true to two brothers products, this was easy to install and sounds great. May 26, 2015
Perfect! This twobros is awesome! Shipping was fast and was exactly what I wanted. Its a plus that it comes w a servo buddy! Only bad thing was that twobros didn't send hardware for rear clamp. No biggie though, a quick trip to hardware store and it was good to go! Looks amazing and sounds just as good as it looks! Revzilla is awesome too! May 4, 2015
Love It! Love Two Brothers! Looks great & Sounds even better! I could notice the hp change and the change in weight immediately. My bike was pretty nimble before so that made a big difference! October 27, 2014
