double exhaust

[jimyd23]

what is the differance of a crf250r's double exhaust compared to a single exhaust like on a yz250f. some pros or cons. what does it povide/do.

thanks.

[Shhhh]

I don't have a dual exhaust bike....seems that it would cost a lot more to replace/repair, buying two slip ons instead of one seems silly to me.

It provides more weight, more things to break and more silencers to repack. I do have to say that they do look kinda cool when they are carbon fiber.

Since the two pipes are so much shorter, it apparently moves the weight towards the center of the bike, making it have better handling, or at least it should. The two pipes also makes it quieter.

In my opinion, it looks pretty sweet.

I thought it was a cr250f that had the double exhaust

Marketing gimmick

Agreed...didn't want to say it though..?

It was a poor excercise of "equal weight distribution/balance" as per the advertising.

[jimyd23]

so in the end there isn't mutch advantages to a double exhaust except they look great

And are quieter...relatively speaking...and cost more...

true it would be quite expensive to repair both and maintain them. would you reckon it is worth it

no its the crf250r that has two exhaust pipes

[orangyktmthing]

They are a marketing gimmick for sure. I understand quieter, but my thought on that is exhaust gasses, like electricity, take the path of least resistance. I would think with more restriction on the silencer section, it would choke it up, too. I have had a chance to see a crf 450r (not ride one though, they don't really intrigue me) and the exit on the silencer is SO SMALL! I guess that is one way that they equal the flow to a single silencer system. Those stock silencers would use 2 stroke silencer plugs, they are that small. Plus, the single silencer full system from procircuit, amongst other companies, are knocking about three pounds off the bike by going with one silencer.

the double exhaust was only manufactured on the crf250r from 2006 to 2009 models then they went back to one. this was a good choice.

Nope...not for me.

the 2014 250r will have dual exhaust as well. I was gonna convert mine to single but the cost of doing it right isnt justified and the duals with aftermarket exhaust looks good and sounds good

Good choice? Why, please do tell?

Also allows more exhaust to move through. But its heavier and more bulky. I switched to a single FMF full system, saw much more power gains and also sounds better ha

I went back and forth with slip-on silencers and they did not so anything. In fact I thought the bike ran worse with them. Then I bought a full single system. Wow what a difference. Don't waste money a slip on. The duals was and is an attempt to center the mass of the bike, not sure if it the average rider could tell the difference

Because its a pain in the ass....everything about it.
