Exhausts, Air filters and Power Commanders

[TimT]

evening all,

I want to put an after market can and air filter on my cbr 600 F2, i have been looking at Akrapovic or Arrow exhausts as i've read good reviews on these. Any advice about either of these would be good also if anyone has any other make i should consider please let me know? Does anyone know if the cbr 600 f sport exhaust is the same fitment as the F2?
Not to sure which air filter is best been told k&n are the best to go for? but then thats probably because my friend has one on his bike!
If i put these on do i need a power commander to make the engine run correctly as i've been told by some people i will and others say because my bike has fuel injection the ecu will automatically correct the air/fuel ratio?
cheers for any help.

The sport is a different bike so i wouldn't recomend buying a sport and fitting it to an f2!

Aka s are sooo much better quality than the arrows, most are titanium with either carbon or titanium sleve, and sound so much nicer than the arrows

but are a lot more cash

i seem to remember someone saying BMC race filters are best for akas and k and n for arrows and picercross for micron? but dunno on what that was based!

as for power commander i don't know enouth about them yet but you bike will undoubtedly be better with one as you can tune the maps to your riding style.

Power commanders will make it run alot better. I watched a demonstration at Dynojet near Preston a while ago. Demonstrated what a Power commander does, compared to just ECU. Basically, ECU won't let the bike run dangerously lean, but the the Power Commander will make it (when properly setup) run spot on!

Buy your power commander from the states too, I got mine, brand new, for £125 delivered, throw in tax and it still works out cheaper.

cheers for the replies, my friend is going states to work for 3 weeks soon so will see if he can bring me a power commander back!
i thought the sport and the f2 were the same with just a few suspension mods and different seat unit?

Didn't the sport get different engine parts to help with super sport racing??

Differences between the sport and normal CBR600F, in short, quite a lot, so I'd buy one for your bike.

Hi

Would think the ECU would freak if you fitted a power commander but left the lambda probe feedback in place. It would decide it was running rich, so lean off the mixture by about as much as the power commander was richening it. Quite possibly out of the range of the allowable adjustment, and quite possibly triggering a fault code of some kind.

All the best

I run a pcIII a k&n and a yoshi have seen a 7hp increase

The main reason I got the pcIII was because it run lean in the first 2500 rpm and lean in the top end so it hesitated a bit.

Now it runs sweet.
