I have a 06 S2R1000 and am wondering what happens to the power range when a full Arrow (carbon) system and K&N filter is installed. I will NOT be installing a Power Commander.

I ask this because several years ago I installed a K&N filter and a Two Brothers exhaust system on my BMW S bike and it killed the mid range. The Two Brothers system was crap!

On one of my other BMW S bikes I installed a Staintune, K&N, and FIM power chip and did not loose the midrange. The Two Brothers system was just noisy and killed the mid range performance.

I have heard that “race” systems like the Arrow will kill the midrange and increase the top end (What I do not need on the street). What have all of you Arrow owners experienced?

Thanks all,

Rob

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 thinking about getting Arrow full system 4 my s2r1K. I'll probably go with a Power Commander and a custom map, too. I am gonna sob a little when I spend all that cash money, but I think it's gonna be worth 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

It will kill the midrange. I know from personal experience. Runs rough because there ain't enough fuel. Forget the PC and get a RapidBike. You will be amazed at the difference.

Hey guys! I have had the arrow system on my S4RS, and I have a much simpler solution than Power Commander. Techlusion Box, this way you can still adjust the mixture. It worked wonders on my bike larger punch everywhere in the range (very streetable) and holy crap HP on top. I am also going to take this chance to say I just sold the S4RS and I have the System, Techlusion box, and BMC air filter. So if you are interested drop me a line!

Techlusion Box... PC III, Rapid Bike, Techlusion Box... so many choices....
Will Arrow full system for S4RS fit on S2R1k? I think midpipe may not fit...
How much would u be willing to sell the stuff for anyways?

Well about the system's compatibility, I'm not sure. As to the cost... well the whole system has about 4,000 miles on it but I would be willing to part with the Full System, Techlusion box, and Air filter for $1,000.. I have after all gotten a lot of help from the guys on this board. Let me know what you think.

2007 S2R1K with the full ARROW system, O2 sensor disconnected. My bike runs much better than stock. I can't tell if it's making more power, but certainly not less. I could likely add a pipercross or K&N air filter, as the bike runs a little rich with the O2 removed.

I'd find this odd as they come from the factory on the lean side for emissions purposes. Don't see where removing the O2 sensor is going to richen it and CERTAINLY not to a point where it would be richer AFTER adding a higher flowing exhaust.

Have you had it tested, or purely speculating?

I'm running a full Arrows Ti setup with the stock baffles and it seems to have a bit of a lean pop on decel so .................... (O2 connected)

Hey Caboose,,,

Two questions:
1. Baffles in or out
2. You didn't list any ECU or RB or fueling upgrade... So did you just bolt the exhaust on and leave it with no fueling adjustments ?

Thankfully my stock S2R1000, with sensor disconnected, fueling is perfect.

Thanks

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.

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

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.

Thanks for the response, I had heard as much, but its nice to get feedback from people who actually have this setup.

I'll have to give it a try pulling my O2 sensor net chance I get and see how the other "bad o2 sensor" map does. When I installed my exhaust i reinstalled the sensor so to give the system a chance to work as designed. Hasn't been bad but haven't seen any great improvement (looks and sound) either.

What would really help this forum is to get actual dyno runs on some of these setups. You've got an incredible mix of experience on this one thread but no real data. I'm paying $75 for HP, TQ and AF runs and I was quoted a low of $60 and a high of $90 (two local HD dealers). This is chump change when we consider what we're dumping into these bikes and the information is incredibly valuable.

In fact a sticky listing setup and #s would be extremely helpful. Keep the posts short with bullets on what's been done and what the chart looks like. If you don't have before numbers don't worry about it, post what you have. No flame outs allowed, it's not a competition, just share your experience with your setup.

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.

Excellent price, but I have to pass for now. I'd love to, but finances dictate making this purchase sometime next year.

looks like now they have some hills on dynos [laugh]
and that plug looks "perfect", in my opinion you'll have to carry a new set and socket when riding (like when we used to ride 2 smoke)

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.
