so i want to get the R77 Yoshi.

i was wondering if there's a way to get two on it.

like one on each side.

possible? if so how?

No, this is not possible. The Honda CBR250 is a Single cylinder engine, meaning it has only one exhaust port. One exhaust port = 1 exhaust header
could you put a splitter of some kind?

anything is possible. its just a matter of what would be the easiest most efficient way of doing so.
I'm not educated enough with exhaust systems to say for sure but I think splitting the exhaust might cause flow & back pressure problems, possibly killing the torque and basically make the bike run like crap. Exhausts need a certain amount of back pressure & a certain flow velocity to do their job. Length & diameter of the pipes play a huge role in this.

I suppose a crafty & skilled person could fab a 'dummy pipe'.
It would be a lot of work, time & money for just looks.

From Thailand. Believe only one is used with the other being for 'ornamental' value I guess.

That looks amazing.

i guess its quite a big investment to have for just looks. but i think it might be worth the looks.
especially if you take the silencer out. it'll be loud enough to compensate for the other side too.

hm...so how do i go about this? haha
I'm curious as to how the other side looks
This is a single cylinder motorcycle. This will only add to the weight of the bike thus diminishing your hp/weight ratio and the money in your wallet. NO. NO. NO.
Ahh, Thai bikes... Blacked out turn signals and tail light, no mirrors, and exhaust hanger hanging high pipes in a place where they aren't supposed to be. So glad I don't drive to driver a bike over there, lol

The bonus of having no speed limits or police. Freedom beats a nannystate any day. :D
i've always wanted to see what the 250 looked like with a high mount setup... but after seeing it and with the small diameter pipe im not a fan anymore. I'll stick with getting a shorty muffler or a gp style pipe
i reckon it will look good with the large pipes.

or even if they arent so high up.

where the normal R77 would be, but just having one on the other side. would be really nice.
Personally I feel the whole rear is the only part of the bike which isn't aesthetically pleasing.

All that plastic could go and a nice slim fairing replace it. Personally I find the rear of the ninja 250 much nicer looking. Have seen a few CBR250Rs with race style fairings on them, so hopefully a few different ones will be available in the future.
^ you and me both, just that lil plastic that comes out under the tail could be tucked away nicely for a more aggressive look

Yes, I looked at getting rid of it but the actual rear fairing connects onto that, then that onto the frame.

Now this is just a photochop of the bike placed over the frame of another, but gives an idea of what the rear would look like without all that plastic.



Would be much nicer ending at the rear seat with LED light just under imo.

A body kit from Indonesia I think.

2007 HONDA CRF250 single has dual pipes.

2007 Honda CRF250R

- Dual-muffler exhaust system centralizes mass and reduces turning inertia to improve the lightweight feel of the bike.
- Dual-muffler exhaust system also increases low-rpm torque.
- Exhaust system uses a lightweight stainless exhaust header and repackable aluminum mufflers.
i like the look, im a big fan of the dual exaust look, but like it also looks expensive..sweet pics though..
I'd feel a bit silly with something like that on such an underpowered bike. I think I'd be looking the other way if someone on a 600 pulled up next to me at the lights. :)
