- We dyno test the full Yoshimura rs12 exhaust system vs stock on this CRF250R
Exhausts are often the first item bought for performane upgrades, but are they worth the money!?
Let's try and answer that in this video!
That’s a pretty good gain in power through out the power band on the yoshimura exhaust
this day and age is a really good gain!
1 hp through some of the powerband for over a grand doesnt seem great lol
@lindseyhunt1090garageb what would you suggest for 1 hp gain that costs less?
@@HPRaceDevelopment nothing. It just seems redundant. Miss the 2 stroke carb days when a pipe could actually add power / torque and change the power band depending on riding style as well as tune the carb to gain power. Those were good times.
@@lindseyhunt1090garageb Right on, sadly I think people underestimate true inflation over the years. A 1k pipe is the same price a 350 pipe and silencer were in 1995
Somehow oems have managed to just make way less and still keep 2t pipes kinda cheap - but i can tell you 100 percent the r&d time into 2t pipes is way down too
Good vid. Have you dyno'd the Pro Circuit system on this bike?
I have not
Do you have to change the fuel mapping on these bikes when installing the full Yoshi exhaust? I just bought a 2023 250-R and want to swap out the exhaust but don't wanna mess anything up.
you dont HAVE to do anything. If you want best performance - an ecu is generally the best first thing to buy
Is the SS version a lot heavier than stock? Would you recommend the Ti system for this reason? Thanks.
Yes SS is heavier. While power is great, every 8lbs of weight is 1 hp. AKA if you make .25 hp and gain 2 lbs you gained no performance in acceleration but lost breaking and cornering
@@HPRaceDevelopment - so the SS system not worth it then in real world use? It's more than 2lbs heavier than stock.......
@@ThePeteGray the power gains are essentially negated by the weight gain...from a power to weight stand point. That doesn't take into account a braking or handling effect. IMHO, NO. Nothing that adds weight is worth it, even if it made 1 hp
I got a crf 450. Do u think that you will have one of those coming through. Love the vids
450s are rare for dyno work. most people want them slower
Which get ecu fits the 22.5 ktm 250 factory edition because looking on your website I didn't see any that specified that it fit it.
shoot us an email we have our custom set up for it
@@HPRaceDevelopment how much does it cost I am thinking about saving up the next month or two.

Ok thank you I may look into one around December I will have to see👍
Nice video..i think you meant 250R and not 250F but yes its written in the title of the video
junk ass bike names
u know what it is
My guy
What sort of db are the yoshi pipes? Some tracks by me have noise limits
I don't measure, sorry! For supercross it has been hard to pass regulations on most consumer pipes.
What dyno tuner did you use? I got a 2023 crf 450 and can’t find a tuner for it
GET ECU, available on the website
Were these numbers taken with the baffle out?
Tested both ways - as shown is baffle out. Out is louder and changes tune up some - but about equal in hp as in
how much more horsepower did the yosh produce than stock
In the video.
I got a 2023rx and I’m leaning towards fmfs factory 4.1 full system can you do a dyno on that exhaust
buy it and send it in, ill dyno it for you.
Can u tune the stock ecu
we prefer to tune aftermarket, stock on hondas has very limited tuning ability
was that a titanium or steel exhaust and pipe
stainless on this pipe
