Arrow Exhaust - Slip ons

[ctrain]

I've been looking into a new exhaust for my 2006 S2R 1000. I think I've narrowed it down to either Arrow or Termignoni. The Termis are quite a bit more expensive but come with an ECU and an air filter the Arrows do not.

For those of you who have Arrows, have you had any issues with running them on your stock ECU? Have you upgraded your ECU? I think if i was to need a new ECU in the future Id rather just go with the Termis and get it all at once. But if there arent any issues running stock then id rather save the $$$ and put it towards something else.

  As long as your airbox and filter remains stock you should  have no problems with the stock ecu.
