Nice pipe dguy. As an owner of a Red/Silver who's close to getting an exhaust, I must admit I would probably go in the opposite direction and get the base aluminum (a half a pound won't kill me and I like the matching of silver to silver), but that's just personal taste.
While we're on the topic, I have a question for those familiar with 2 Brothers exhausts: what are the tangible differences between the Black series and the regular exhausts? From their website:

If that's it, I guess the only real measurable difference aside from looks is possible longevity of these parts? Otherwise happy to be corrected.

^ as far as i can tell the only difference is the color of the "inlet/outlet", bands and the bolts, the standard 2bros also has magnesium end cap.
2bros also now do a full system.

Alright so, this thread's already here and I've already posted in it so I figured I wouldn't clog the forum with another one of these. Yesterday morning, I went ahead and ordered my own Black Series 2Bros can (Aluminum option, because I actually prefer that look which makes me weird I know). It was ordered from Biohazard Cycles, who I'm not going to link but they advertise on this forum. The exhaust arrived via UPS today (I live in Oklahoma), and I went and installed it after riding home from work and letting the bike cool down for an hour or so while I read the instructions. Aside from an adjustable wrench and a willingness to read between the lines of some of the more vague instructions, everything I needed came with the box. I chose to leave the suppressor tip IN for now, maybe I'll test it without later just for kicks. Of course next I went for a ride! It was quite dark when I came back so I don't have pictures of the pipe just yet but I'll add them tomorrow.
Speaking only from about 2 hours and 15 miles of ownership since I saw the box waiting for me at my door, I can say I'm really digging this exhaust! It sounds quite mean at idle from the perspective of standing away from the bike, sort of like if you had your ear pressed up to an irritated lion growling inside a metal box built much too small for it. I saddled up and put the bike into first gear to leave the lot and the exhaust note got a bit more sedate, up until I hit maybe 5k RPMs. From there, a sufficiently eager throttle hand while accelerating through first gear and into second had the bike producing a wonderful crackling roar. It was also possible I discovered on a test to keep the noise sedated with gentler acceleration, if you're worried about startling the neighborhood.
Biggest thing I noticed: a lot of the extra exhaust noise was really up to me, as a choice of what Gear (and subsequently, RPM) I chose to use to make my desired speed.
Once established at a higher gear for cruising speed, I was pleasantly surprised to find that it doesn't sound much louder then the stock exhaust... just deeper and throatier. If you need to bark your approach at an intersection, dropping gears and giving the throttle a quick flex will very much do the trick. People noticed! This is of course completely anecdotal, but I felt like cars were going a bit more out of their way to leave me lanes on the highway. Maybe it had something to do with sounding almost like a proper sportbike, maybe not. Another advantage is that engine braking is a lot more fun now. The pressure differential caused intermittent pops of backfire that were just as tasty as the rest of the new sound effects.
Performance-wise, I understand it will take a day or so more for the O2 sensor to catch up with and properly match the new fuel-air mixture. I wasn't trying to run a scientific analysis while riding but it did feel like I held 40 mph and then 60 at what seemed a lower rpm then was normal, although this is again entirely subjective and might have just been the exhaust sound and my happy grin playing tricks with my head.
So to summarize, love the exhaust already, and MAJOR props to Biohazard Cycles! I had a tracking number in my e-mail the same day I placed my order and everything went without a hitch, thanks a ton guys!

Whats with the 50c pipe clip? Looks shocking if you ask me, one of the reasons I went FMF. http://www.cbr250.net/forum/cbr250-parts-accessories/2521-fmf-exhaust.html

Hi Biohazard,
I looked at your site and I like the look of the chrome Yoshi exhaust the best, the M4 Shorty with a strong second.
Do you know if either pipe stays clear at a low speed drop? I mean, I purchase a 905 crash cage for the front, and if I get either of these exhausts, will they get scratched up if I accidentely drop the bike standing still?
I am 85 lbs and the bike is currently being lowered with the full soupy kit with the kickstand. Pretty sure I will be at 3 or 4 inches to feel comfortable.
But I have never ridden before so I am afraid my nice shiny red bike is going to take a few dumps, should I wait on the exhaust or buy it now? I was thinking it might help me 'hear' the gears if that makes any sense.

i would tell you to ask someone in the general section.. as i dont have a 250 here in the shop to check it 
i would think it would prob still get damaged ..
i would think it would prob still get damaged ..[long response for novice - typical for and against etc,
just scroll on bye
littleingrid - there are arguments both ways..
is you sell or trade her at some point its better
to have the original muffler, so from that point of view
you could store the pristine original, for later..
these bikes dont take too much damage from side drops,
partly because their design includes that possibility..
honda tests everything in its designs, including
side drops, which can be seen in how levers,
bar ends, flexible indicator stalks, foot pegs
side under seat fairing part and muffler shield
all take impact from side drops..
mine has gone down at almost standstill on her
leo vince evo carbon slip-on with hardly anything..
it has also taken a solid hit from a moving car
[enough to jump the rear wheel half a meter sideways]
with only a paint mark from the car and zero damage..
good slip ons are well designed and tight fitting
[another reason they look good] and no doubt
have also been variously drop tested on bikes..
as for hearing the engine to help with gear changing,
while this sounds like a handy learning aid, you can
or someone can ride while deaf or wearing ear plugs..
heaps of sensory data is flowing from many, sensors
thruout your body into brain, as it [eagerly] learns
'the new thing' - which is inherently interesting/exciting..
when you do your practicing somewhere quiet away from
traffic and distractions, you will be taking it fairly easily
at first, while brain starts to make sense of it all..
it doesnt take all that long [the more you practice, etc]
to know when its time to change up or down gears..
even with the quiet stock exhaust you will still hear this..
slip-ons with noise inserts especially when ridden off load
at around or near her max torque ['pulling power'] range
say, 4 - 6krpm dont need heavy throttle just riding along
so dont make the louder noise of an engine under load
[such as taking off quickly or uphill etc]
so theres not really that much difference then..
your eyes will see the road ahead, and with practice
see with quick glances the tachometer for revs
[and speed] plus side mirrors and whats behind etc..
brain quickly becomes aware of what certain revs mean
and as relate to particular gears and speeds etc..
just by doing it,, just riding up and down, and around
over and over again in easy practice, this will happen..
there is a fairly wide latitude between possible engine revs,
gear selection, and speed, together with the road conditions etc..
its not all that important to be precise in a particular rev or gear
or speed combo - especially when learning the bike..
in fact everything including missed shifts or whatever
will all be translated as sensory data into brain,
ie, part of the learning..
slip ons are much lighter than the stock exhaust..
weight = horsepower, or as an end result..
so she will feel a little bit lighter, which should
also make slight differences to power output
or giving a slight edge to responses in some
situations [exiting corners under acceleration
was noticeable with my leo vince evoII]..
but really, theres hardly any significant difference
on the road, esp for learning the motorcycle..
people go for exhaust changes for various reasons,
which might not be where youre coming from..
and there are other mods to stock worth considering
before going for a slip-on, such as [imo] a louder
horn,, with a range of types and loudness available
for this bike [mine under $20 thru amazon] easily
installed with or without relays..
personally tho,, the first time i laid eyes on black beauty
the one thing that stood out like a sore thumb
was that oversize, heavy, incongrous add-on
design muffler.. it just looked like a great honda
motorcycle with something added to the original
honda design.. which it is, basically..
mine does, make more noise tho, especially when
under load such as accelerating, taking off from lights
[i frequently filter to the front between cars, now legal here]
to get quickly into clear open road space, plus overtaking
similarly and riding up hills [or with a passenger onboard]..
so there is that.. its not 'the nicest people' quietness..
but with sound reducers installed its acceptable [not to all]..
for me aside from those loadings she can be easily ridden
within low noise ranges in typical backstreet or traffic
situations.. so you can make it, make noise..
here is one area where even tho perhaps minor
there is a real advantage in being able to make noise,
as you think it, more quickly than going for the horn..
ive had a bloke carrying a little baby, engrossed in it,
step onto the road the other side of the small roundabout
i was entering,, which a quick strong blip of the throttle
had the desired effect, he froze on the spot, one foot
on the road.. there are plenty of situations where you
might want to let it be known your existence there
for one reason or another..
these situations go beyond considerations for
making a nuisance by being noisy..
ie, the ability to make some noise
can be a benefit and tool for the
sensible rider..
so if you do go for the slip on, go for a good
brand [search box her full of info etc]
and put the stock muffler away somewhere
to be re-installed later if necessary..
[they also cost a fortune to buy]

Thanks shisoshin, that was a long read but touched on a lot of good points. Mainly the resale value. I just wish there was a way to pull out the catalytic converter on the stock exhaust to be easily reinstalled, and a slider that protected the exhaust, then I would be set.
I am probably going to get the Yoshi since its like $300 delivered and sounds great on youtube, I also like that it looks decent and matched the grey a bit, the black doesn't quite go with the whole schema. That just an opinion, but its my bike so its the right opinion! hah!

li - on side drops, firstly dont assume you will drop her..
dropped mine cold while parking on my steep home street,
it was just that fine line which the downhill [ie, its gravity]
overcame her balance momentarily, and i wasnt able to
defeat gravity and her mass.. but never dropped any of
my previous 4 honda road bikes or any other bike..
the main thing is to become very familiar with her vertical
alignment and center of gravity [becoming 'part of it']
which is easily started by simple practice, engine off..
start by standing next to her holding bars, hips on tank
or seat, stand down, then begin gradually taking her weight
my pressing down with your feet/legs gently which will allow
you to feel her weight, flowing into your hips down to feet..
every time you do this,, your brain will receive masses of
sensory data including from your inner ear and balance
mechanism.. when comfortable with this small movement,
try it eyes closed.. same thing, repeated eyes closed..
this is the basic method you can apply to both sides,
with one leg up [such as lifting or swing one leg up
as you would for mounting generally] pausing with
let touching the seat [mimicing any such pause]..
this could progress to pushing her forward a bit,
then easing her back again,, and so on..
then just sitting on her, as you would normally..
taking the weight both sides or if you cant reach
one side, stretching leg/foot down as if about to..
then just lifting one foot or toe off the ground
while the other foot takes the weight..
just repeating that, for hours if you like..
the more you practice holding her weight with both
arms/hands/legs/feet assisted by all torso muscles
not only will your control and balance improve
and become reliable, but every, muscle and joint
you use, will be switched on [perhaps for some
of them the only time during a typical day]
and they will become progressively stronger..
whether your a skinny girl or big weightlifter..
also, even tho you might not practice lowering her
to the ground, the more you practice these basics
the more likely you will be to keep some control
of her weight if she ever does drop into gravity,
thus, even if its too much to lift back up
you can still help eases her down somewhat
by taking the weight with all those muscles
youve been preparing.. one way to practice
for this is to place one foot wider one side
then without actually taking all the weight,
let your leg/foot take a bit more weight
[just a bit] then back to vertical..
lots of text to describe these simple movements
even basically, but starting simple you can,
develop pretty good drop proofing..
when you pick up a pen [say] you no longer need to
adjust your fingers and thumb on it to hold it properly..
it becomes second nature.. same for touch typing etc etc..
and the same for managing your motorcycle/its verticality..
to check where contact points are for a side drop
get an old door or any similar sheeting and place it
against both tyres where they touch the floor
[lay it on the floor to start if you like]
then just lift it upwards, keeping the other side
touching both tyres.. you will see where it touches..
this will show contact points such as footpegs,
which take the first impact, lessening it..
to find the next contact points, just pivot the
door/sheet upwards around first contact points or pegs..
scratches on lever ends, bar end sliders, peg mounts etc
are not such a big thing anyway.. sort of battle scars..
and you might be lucky anyway
and drop her on the other side..
