Superbike styling right from Yoshimura Suzuki Road Racing! The trapezoidal shape is all business but as racing enhances the breed – the result function driven shape makes for a beautiful muffler. The R-77 delivers better performance overall because of the larger volume of packing material available due to its design. Finally, a great sound comes from the R-77 – not loud, but throaty.
The R-77 features a straight baffle with removable low volume insert. The muffler’s front-cap is MIG-welded while the end-cap is riveted using high-end 304-L polished stainless steel rivets and bands. It was a perfect choice for Honda's new 500cc line-up!
Note: This exhaust is CARB compliant. Please check local laws before purchasing. Some modifications may be prohibited in some states.

Brett D: It isn't as loud as the twin brothers exhaust but it has a much better sound. My 500x sounds more like the V Twin it is and not a scooter.Jan 17, 2015
David C: After a great deal of evaluation on YouTube and bike specific forums, my subjective impression was that the Yoshimura offered the best sound and look. The fact that the sound reducing baffle could be easily installed with one screw (as opposed to a rivet) was also a factor. Finally, in terms of bike resale value, most people seemed to prefer Yoshimura.Jan 11, 2015
David B: The name and the reviews. Very happy with purchase!Dec 8, 2014
Ryan G: I talked to many people who had sport bikes and Yoshi exhaust systems tended to be at the top of everyones charts for which one is best. So I got the best for my bike.Sep 5, 2014
Richard L: Yoshimura is a quality company and having a little more sound helps the drivers of cars around you to know you are there.Aug 8, 2014
A B: It was between this and another brand but after some research and listening to the sound on youtube it was an obvious choice for me which one I wanted so I got it.May 12, 2014
Dwayne B: Great looks and price plus other reviews were extremely helpful.Apr 20, 2014
Timothy W: Replaced stock muffler after crashMar 19, 2014
Joseph P: Needed something louder with style.Mar 7, 2014
Vincent T: After research, yoshi was my only choice! Sexy carbon! and the it roars like a beast! bye bye stock :DDec 23, 2013
A shopper asked:Does this have a stop so I can still use the center stand on my CB500X?Aug 4, 2014
joseph r:Yes, my opinion it sounds a lot better without it. It comes without it installed from the factory, so you would have to install it yourself after you put the exhaust on your bike, it's easy just 1 screw.May 1, 2014
Dwayne B:You would have to check with you lacal noise ordnance. It does come with an insert to make it quieter but I have never used it. I don't really have a problem with it being loud and awesome. Hope I helped.Oct 17, 2014
Tchon M:No, it even has a sticker on the muffler that says that when you get it. That being said you would have to have the worst luck in the world for a Police Office/Sheriff or CHP to give you a ticket for it. Unless you doing wheelies in the intersection of you town. I even had the Local Honda Dealer install it for me without an issue. Sound is great and I even get a bit better MPG.Oct 17, 2014
J U:My wife has a Two Brothers M2 Black Series on her CBR500R and I have the Yoshimura on my CBR500RA. The answer is the Two Brothers seems a bit louder but the sound of the Yoshimura I personally like better. I also believe the carbon fiber Yoshimura looks much better but the Two Brothers appears to give my wife's bike a bit more punch, even though I also have the DNA Performance Air Filter.
Brooks D:I didn't do a pre and post dyno. The reality is that the biggest change is clearly the sound. Now does that sound impact how aggressively you throttle control or you perception of what's happening? Dunno - it certainly feels that way.
Yoshi does offer a dyno curve on what the slipon is supposed to give you. It doesn't show a ton of lift and you have to suppose they are cherry picking to get that. The reality is that in a bike with mid 40s HP if you pick up 1 HP you got a 2-2.5% increase (probably on the bottom end of noticeable).
All that said, some of the best money I've ever spent. Sounds great. Looks great and changes my perception of what I'm riding from a vacuum cleaner to a sport bike!Oct 15, 2013
Thomas O:After placing the Yoshi R77 slip-on to my CBR500R, I noticed an increase of approximately 5 - 8% HP. Doesn't seem much but it feels much faster than with the stock exhaust! However, if you install the full system, you may get up to 10% HP but you'll be paying between $1000 to $1200! I don't think it's worth the extra cash for little increase in HP between a slip-on & a full system. Plus, after doing research on different exhausts, The Yoshi sounds better compared to Two Bros, Akrapovic, and Leo Vince! The only exhaust I actually considered to buy but was over my budget was the M4.
Michael D:I do not know if it is legal in europe, but it is legal in california, the hippie republic of america. It isn't to loud and there is an additional silencer provided. Very nice exhaust, well made, and easy to install. Worth the money.Feb 11, 2015
A shopper asked:Hi, The Two Brothers exhaust says do not use with saddle bags. The Youshi does not say anything about that. I have saddle bags on my X. Does anyone know if it is OK to use the Yoshi with Honda saddle bags? Thanks.Dec 28, 2013
A shopper asked:Does the optional baffle insert affect the low end torque, hp, or top speed of the cbr500r? I just installed the carbon r77 slip on and it came without the baffle pre-installed. Thanks!Dec 17, 2013
Brooks D:So let me start by saying that I think the r77 is a fantastic mod to the CBR500. I love mine. The bike sounds better and looks better. Is there more low end torque, hp or top end speed with (or without the baffle)? I can't really say. Yoshi's dyno graphs would suggest that they do, but certainly don't show anything overwhelming. Also it is worth noting that Yoshi has a vested interest in making that improvement as large as possible. All of which is to say, I seriously doubt the added back pressure of baffle is going to change things much one way or another (or at least at a level you'd notice or could measure).
What I would say is measurable is the added enthusiasm you have to turning your wrist when the sound changes from the vacuum cleaner stock exhaust to the sweet sounding Yoshi slip on.
Highly recommend the slip on. If you are worried about it, leave the baffle out. The bike isn't loud either way!Dec 17, 2013
