where to go for power in 2009 R6?????????

Hi i have an 2009 R6 iam looking for more power just wondering where to throw my money before going internal.
i have a gytr slip on and k&n air filter at this stage. next on the list was a power commander 5 but am now throwing up whether its worth putting on extractors first??? if there is that much power in them as id rather get one tune on powercommander.
the other thing i have heard was the 520 conversion at this stage i have already dropped a tooth of the front sprocket and am not overly interested in it revving more in top gear nor changing gears more. for the reason of easier power wheelie doesnt bother me as clutching is fine  

The Power Commander should be at the top of your list.
With a K&N and a slip-on your bike probably lost power from stock because the air/fuel mix will be messed up.  

yeh i sussed out mjs performance and they do a great deal on headers and power commander with a map. sp will give that a go i think and then maybe look into a retune if i find somebody real good at it here on te east side of Australia
