[Riv]

Hello,
I'm about to buy the Akrapovic Racing System for my R12S and I have doubt about the needs or not of a additional control unit like Rapidbike or Powercommander.
I wrote an email to Akrapovic who answered this:


Dear Costumer,

thank you for interesting in our products.



All of our exhaust systems The Bolt-On, Slip-On, Sport Production, Racing, Evolution and

Street Legal lines are designed to function properly using the stock carburetor or electronic

fuel injection set-ups. This means that no changes to the stock set-ups are necessary in

order to use Akrapovic exhaust systems. Also, all of the performance specifications which

we measure and list for each exhaust system model are based on stock set-ups. We

assume full responsibility for the accuracy of these specifications.

Visit our site for more information.

Best regards

Akrapovic R&D team



Now, I have the Akrapovic Ti Slip-On on my R12S and K&N airfilter and everything runs fine even at some rpms delivery is a bit flat ...(however better than stock!)
Can I be quiet sure about the improvement at low-medium rpms declered by Akrapovic?
Anyone has experience?

Thank you all for any answers
