Yoshimura R-77 Slip-On Exhaust Honda CBR 500 R / CB 500 F
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.

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.
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
