I have the givi racks for E41 cases, it looks like the pipes will slide out without taking the racks off?
Or am i dreaming
I find they need to turn/twist a little to get separation from the header pipe.
With the Remus pipes there is no packing gasket. Metal to metal, so not a lot of give.
You can sure give it a try. Lets know how you get on.
