I'm running Arrows on mine with stock airbox & ECU & my mid range is fine. No noticeable loss but I haven't dyno'd it so I can't give you hard #'s. Seems to be a little lean but that's about it.

I am running a full Arrow Ti system with the baffles in. I like the baffles as they give a little backpressure and I seem to be able to get by without any major tuning. It sounds great, nice throaty sound, and seems to have a bit more power. I have not done any tuning to it yet.
Eventually I will probably go with the Rapidbike III and a K&N filter.
When I do this I will add another hole into the baffles and open the airbox just a tad.
I'll then set up two maps for the system, one baffles in and open airbox(track), and another with airbox on/baffles in (street).
I have grown past the stage of having a fully uncorked bike for street use. All an uncorked bike does is piss off large parts of the general public, endangering our sport, damages your hearing and tires you out prematurely. Save the uncorked bikes for the track, your neighbors will thank you and your children might as well since they may still be able to ride a nice throaty sounding machine because Dad was not an irresponsible prick that helped give all the uptight aholes the ammunition needed to legislate us into oblivion.... [thumbsup]
Think about it........ also doesn't make ANY SENSE to put a full race system on and then say "I'm not going to tune it" Just makes you a real poseur as all you are doing it for is to make noise
If this is your approach to tuning then no wonder you had problems with previous systems :
Excuse me for being so blunt ;D

biensure you'll loose something when you change to full exhaust & K&N...and on long term you'll loose a lot more....

Carby's so no baffles.

Stock ECU...TPS, AF, everything tuned to perfection...well as close as it gets. No mods to the intake side of the bike.There is zero popping on deceleration or any of the other nastiness related to a lean running bike.
My bike runs a tad rich. The smell from the exhaust is notably different at idle. Here's a plug with the motor killed from 8000rpm, throttle WFO.

S2R1K's do come from the factory terribly lean to comply with emission standards. Mine popped on decel when it was bone stock, thought maybe there was an air leak somewhere. But lets make a long story short. Call it limp mode or what have you, but when the ECU gets an O2 trouble code the check engine light comes on and the fueling map changes. A dyno / AF sniffer is not necessary to notice the bike is running differently with the O2 disconnected. The change is dramatic, and in a good way. What do your plugs look like with the O2 connected? Prolly' the same as mine did.....whitish.

Dude, this is the internet. It's nothing but speculation......and porn [thumbsup].motolocopat said:

A big pipe open system doesn't always kill the low mid range and baffles in or out. When the 50 mm system is installed on the testastrata engine it definitely doesn't. Looking at the torque curve below notice how much fatter the torque is on the red trace (baffles out) as compaired to the blue trace (baffles in) from 3600 to 5500 rpm. And after that HP takes over.
And from 5500 onward notice where the stock trace is verses the other two. No loss in power, midrang or otherwise - big gain.

Dude, this was well said. I have an Arrow exhaust on my 07 S2R 1000 and even installed Arrow dB killers cause it was so goddamn loud. Spending money on upgrading your exhaust without tuning your ECU to save money is like pouring a bowl of cereal and skipping the milk to save money.I am running a full Arrow Ti system with the baffles in. I like the baffles as they give a little backpressure and I seem to be able to get by without any major tuning. It sounds great, nice throaty sound, and seems to have a bit more power.
