Product Description

Using the cat for this slip-on?
I have a question about this slip-on, it should fit on a honda cb1000ra 2009 (European model)? And does it fit on the existing cat since I want to keep it and just use the slip-on (I don't want to install a Powercommander and therefor not use the extra "pipe"). I appreciate any help. Best regards, Victor

Yes, for your CB1000R this will eliminate the stock catalytic converter. As with any model, when changing exhaust systems it will vary whether you will need to modify the fuel system based on location, weather and elevation. Typically it is a good idea to utilize a fuel programmer to obtain the best performance, even if it may not be absolutely required.
