Exhaust Options...?

What are typically the best exhuasts to buy aftermarket? Id like something that produces some decent power, isnt overly expensive, and sound is not an issue. I can run the loudest thing out there.

thanks in advance

The popular one for the WR-250R and X seem to be the FMF Powerbomb head pipe along with either the FMF Q4 muffler or Powercore 4 muffler.
The Powercore 4 is the louder of the two.

I've got the header and Q4 on mine, and it works fine and dandy:
Not too loud, lighter, and gave the bike more gnads.
Also looks pretty darn good. :)

If you haven't done so yet, do yourself a favor and eliminate the airbox flapper and install a fuel injection programmer like a Power Commander or FMF Power Programmer.
Bike runs mucho better and stronger, like it would have if it weren't for these crazy EPA regs. :)

Care to explain why noise level is not an issue?

You might also want to define "best".

It is a subjective word after all.

Yeah, 'best' isn't exactly an accurate term when describing this kind of thing; it varies, as what might be 'best' for Mark might not be 'best' for Keith. The general consensus (most popular) seems that with this bike, the FMF Powerbomb/Q4 or PC4 is the exhaust of choice. A few are running Yoshi's, but it seems that in time people have gone to the FMF.

I honestly don't think the PowerCore 4 is that loud. Granted it gets really deep sounding if you lug it. It's way quieter than any Harleys, Sportbikes or Fart Piped Civics around my neighborhood.

Yes, best is not a very good descriptor.

Noise level is not an issue because I like the noise. I will look at the FMF site. Just didnt see any real comparison thread on here for different exhausts.

Ahhhh....it's a free country...but you should really consider not being as noisy as possible.

For one thing, many states are coming down hard on noise levels. Issuing tickets and not allowing vehicles through inspection.

For another thing. It really pisses many people off.
Those people vote. Those people have some level of power.

Excess noise for the sake of noise is not something we as a motorcycle community should be promoting.

Just sayin'.....

Yes. It's the "If we don't police ourselves some one will step in & do it for us". It does happen. But I have not heard the PC firsthand so I don't know if it is ear splitting.

I have. It's noticeably louder IMO.

Ohio doesnt care, and there are zero inspections.

can the fmf slip-on run perfect without any mods or pc? i want to change the slip-on only. will this fit to the stock header?

Its not the state government of Ohio, its the people who live on or near the trail you're ripping around with a loud ass exhaust. These are the people who will get annoyed, and then pissed, and then lobby to the city, county, and state to get your riding areas shut down because of "all those noisy dirt bikers and hooligans are annoying bastards". Ohio doesn't exactly have the best track record in respecting the driving rights of its citizens and others...

I'm personally favoring the GYTR exhaust, I like the option of keeping the heat shield and the slight noise increase along with the power increase.

FMF Q4 includes a sleeve to use with the stock header.

Why is that shewolf?(switching from yoshi to fmf?) Cause i am thinking about ordering the Yoshi RS2 for my wr250r...but have noticed not many people get them? is there anything wrong with them? Why do people get the fmfs over yoshi price? Just wondering if any of you guess have any thoughts on it let me know. I dont want to regret getting one.
I cant use the yoshi pipe without a programer can I?

Thanks

if you are in ohio check out hmf they are out of ohio they are in brook park here is a pic of mine they are $240

I posted a few initial "field test" comments over in the ADVRider monster thread.......I installed a Dubach Can on Friday morning (without quiet core baffle - baffle is on two week back order)........even without the baffle, the sound coming from this little bike is still quieter than my STOCK/Street Legal Ktm cans/bikes.....when it comes to the WR250R, aftermarket exhaust "noise" is a non issue (to me)......

I like the look/fit of the Dubach can and I also like the fact that I can retain the use of the stock heat shield......I don't have enough experience riding the bike in stock form to "feel" any seat of the pants performance gains......but High Five's dyno runs offer objective proof that the performance gains are there with the combination of AIS removal/air box mods/aftermarket can/fuel programmer........that's good enough for me.......... I'd hate to think I dropped ~$500 on a straight "vanity purchase" to get the bike to sound like a motorcycle instead of a juicer/blender on steriods...

Here's a pic I snapped before heading out to the desert Friday afternoon:

i just took off my ais and did the air box mod i can't believe the sound difference the bike is much quieter and got rid of the pops on deceleration the hmf exhaust is still loud but much better

I modded my Q4 down to quieten it a bit and can't say I've lost the low end power benefits. Still sounds good too, just quieter. The only problem is the bike seems to bounce off the rev limiter more than it used to...


btw, you don't HAVE to ride a Harley to be a FAG!

True, especially when riding off-road on county roads with  ranchers, and other private property owners. I am starting to see more locked gates and upset residence around Texas. Stock exhaust is fine...people should spend their money on riding class instead.

What did you do to make it quieter? I'm thinking of making my own DB dawg inside the can upstream of the spark arrestor.

Indeed Gordy, I would also like to know what you did to make your Q4 quieter....

I went with the FMF Megabomb header along with the Q4 and the FMF Power Programmer. Very happy with the package. I was also able to obtain some lower prices online with a little effort.

My easy crusing speed increased 11mph (63 to 74) without any other mods. I have not touched the AIS yet. I now need to raise my sprocket ratio in order to utilize the power. Thinking 13/46...
