IronWarrior I have bluetooth headphones that have the "marshmallow" style foam buds. They aren't quite as effective as proper plugs, but they cut the road noise extremely well, and I can listen to some tunes while riding without having to blast the music as loud as possible to hear it over the wind. I can definitely tell the difference between rides with and without the buds after getting off the bike. I have used in-ear foam plugs as well and find them to be only slightly better than the buds, and without the benefit of tunes.
To those who will inevitably say that listening to music while riding is dangerous because I might not hear something, I can assure you the volume I have set on the music in no way impacts my ability to hear external stimulus than a pair of earplugs. Everything in life is a compromise, and people are willing to accept and mitigate different risks in different ways.

SparkyMJ True that^^ I found that head socks too can reduce helmet noise overall slightly too, helps a bit. I use plugs for any rides longer than commuting if I can remember to.

I do feel that an Akro slip on would give better performance than a danmoto one though, theyre a little more high end...

Been riding my stock pipe since, and it sounds great and feels better.

You're going to end up with a lot worse than tinnitus if you don't ride with ear plugs. Even in a full-face helmet, you should be using ear plugs. Hearing loss is no joke.

TwistedGray How do you guys ride without ear plugs? I did for the first decade or so of riding, but riding with ear plugs (not ear buds) significantly improved my post-ride life. It's night and day...I don't ride with music either. I would prefer to hear things around me and find that I enjoy the ride more without the distraction of music.

SparkyMJ Interesting points.

Yeah I have concluded I want to keep it stock for sure. I wasn't looking for any power gains at all, I just wanted a bit more sound and a bit less weight. But the compromises were too great. Definitely dont have the cash to drop on either a nicer brand slipon, or any exhaust and a fuel controller and intake.

I do ride my bike super frequently, and sometimes add hearing protection, on top of having an RF1200 helmet and headsock (which is a super quieting combination already) but I've concluded that on this bike for me, it wasn't worth the changes.

I was just utterly shocked at *how much* the single slip on could utterly ruin the bikes ride-ability, jeez.

I was able to sell the Danmoto slip on for 100 bucks within hours, so I guess I'll put that into some of the CRG Spectrum RC levers or something else that actually improves the riding experience for this bike lol.

Cheers, thanks for the input guys.

To each their own. I have a Danmoto Carbon MK2 and love it!
The baffle DEFINITELY reduces the sound volume.

I hated the stock pipe, as it sounded too much like a 50cc scooter to me.







Here's a video of the comparison:

ElPasoNinja I have the 2 bros carbon slip on (kinda pricey) and without the baffle it was crazy loud and probably losing some torque due to lack of back pressure or whatever. Got the baffle for it and it's much better, just a bit louder than stock and performance close enough to stock to not matter, get the occasional pop on decel, but not much. In the end, I wish I would have just left the stock exhaust. I love to speed, better to speed quietly than attracting all that unwanted attention from a loud exhaust.

myarza I was on the fence on whether or not to drop some serious money on a slip on. I have mixed feelings about my decision mainly because changing the exhaust led to also dropping money on an air filter and fuel controller. Additional 300 spent. But from my experience the additional cost of the filter and fuel controller was absolutely necessary after installing the exhaust. Without these 2 additional upgrades the bikes “ride ability” imo was worse than stock. The fuel cut off was more abrupt, the throttle was anything but smooth and I also had a lot of back firing during deceleration which was cool at first but quickly became annoying. The fuel controller corrected all 3 issues for me. So why upgrade the exhaust in the first place. For me it was for looks and a little weight savings. I wasn’t at all looking for performance upgrade. But imo if you are going to change the exhaust be prepared to spend more money on additional mods to make everything work right. Honestly with plans on stepping up to a biker bike within the next 2 riding season if I had to do it all again I would have left it stock. But no regrets I love my 300.

Granpooba People can argue the point if they choose to, but here is the scoop. It also came from a good friend that was once upon a time on the Yamaha Factory race team.


Even though that stock muffler on your bike may not meet your appearance, or sound requirements. A lot of factory engineering / test time went into those mufflers to achieve the most performance from the complete engine, muffler package.


Its just that simple. Thus, you are better off sticking with the stock factory mufflers.


UNLESS YOU are into racing " BIG TIME " and doing a lot of mods. Also, what I mean by BIG TIME is that you have a lot of BIG ... $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ , with access to some very good dyno's and test equipment.
