Hallo I have read a lot about aftermarket exhausts for 250's in this Forum. I have a 09 650r and also want to get an aftermarket exhaust.

Does anybody know if this is a good exhaust:

Yoshimura 2009-2011 Kawasaki Ninja 650R / Ninja ER-6n TRS Slip On Exhaust SS/SS (1440265) 2009 2010 2011

I'd like to get one that increases the performance and at the same time is very loud. I really don't want to spend more than $350 either. Can anyone give me any ideas? :thumb:

Thanks

Best bet would be a two brothers, yoshi, or a m4 exhaust and you can get both for what your wanting to spend as a slip on

thanks. did you see the exhaust in the link i provided? is that going to be one that is under the bike like the original one, or would it be sticking way out on the side of the bike?

 

[byte2022]

I couldnt answer that question honestly but ill tell you this. The bigger the opening the louder it will be for the most part

The Yoshi exhausts for our bikes are slung out the side slightly. I have the Yoshi TRC fitted to mine. Slightly different end cap. It should sit the same as the one in your link




I have the silencer fitted to make it a little more muted, but I don't like an obnoxiously load exhaust. It still has a nice rumble though.

A friend had the 2Bros fitted to his 650R, but that was stupidly loud. It looks neater tucked under the bike, but looks are all subjective, and it's up to you what you think looks good.
One tip if you happen to look at the 2Bros system, whatever you do, DO NOT get the Carbon Fibre Canister. It will crack, and break off. I've lost count of the amount of people I have seen complaining about this can, and at the time, 2Bros had not stepped up to the plate to reimburse customers. They may have changed the design since, but I cannot confirm.
The issues supposedly starts from the vibrations of our motors.

I Have the carbon on mine as well as a few of my friends and we havent had any problems at all but i also dont own a 650. .

Yeah, it's been pretty isolated to the Parallel twin engine that has caused them problems.:thumb:

Slightly different end cap. .

Well that's what I am worried about because the muffler i am looking at one that has an end cap like in the picture below, and then there's the other kind you got. So I am wondering what is the difference in sound?

 

[Zandit]

I don't believe there is a difference, it's just a look.

 

[byte2022]

There will definitely be a difference in sound if the exot hole has a different diameter. The smaller te hole the quieter and less deep of a sound. And vice versa for the larger opening

 

[estefano]

well, i'll have to contact the seller and find out how many Db the muffler has. I found another muffler as well with 105 Db. i attached a link. does anyone have any idea how that one is?

I know it's loud and it's only $54 but what about performance and fuel economy?\

 

[byte2022]

Thats not a muffler at all. Thats an exhaust tip. Performance is not gonna be there but the loud sound will. Thats why its as cheap as it is

 

[estefano]

Hey guys, thanks for all your help. I finally made up my mind what exhaust to get and installed it this Saturday. Its a 2Brothers exhaust as seen on the pic. I did not take a picture but it looks basically like on that pic

i installed the exhaust actually twice because the very tip of the fairing is touching the exhaust. And it seems like there was no way of getting around that.

And I i'm also worried about water getting inside the exhaust if I drive in the rain, or if I have the bike standing in the rain. Is there any way at all to prevent that.

Thanks

The fairing touches on mine as well. Simplest solution is placing a couple of washers behind the fairing on the bottom bolt that holds the fairing in place.
If you are wondering which bolt I am referring to, look above at the photo you posted, and draw a straight line from the end of the brake lever. I have two washers behind my fairings, but could probably go with 3 if I replaced the bolt with a longer one.
In terms of water, I don't think it's all that bad an issue, but if you're concerned, get hold of a rubber exhaust plug like they use for dirt bikes. Plug it when not in use, and remove it prior to starting it.

 

[byte2022]

Water is a non issue. If your riding the bike the exhaust gases will be pushing out not allowing water in the bike and when your bike is parked it may get water in it but it will come out when you crank the bike and the moisture left In the can will come Out as the bike runs in the form of steam. How do you like the sound? Is it what you were looking for

Man, the sound is better than expected. It sounds really nice and if people don't see me coming down the road, at least they hear me now

That's a great idea. Why didn't I think of that? :facepalm:
