  • The R-77D boasts a carbon fiber cone end-cap and polished stainless steel dual outlet turndown.

  • This Slip-on system includes R-77D muffler, stainless steel mid-pipe, installation hardware, and step-by-step instructions.

They do not mention needing a fuel tuner product, but it is highly recommended to get the Air/Fuel mixture ratio back to optimal performance.

Q: Using the cat for this slip-on?
2 years 4 months ago
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

A: 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.
