I ordered a set of 3.5" tip compatible Rush mufflers for my true duals. I like the look of the fishtails but they are not available from Rush anymore. Does anyone know if the pre-2007 Screamin' Eagle fishtail end caps will fit the Rush mufflers with no modifications?

 

Thanks for choosing Rush! The pre-07 tips will fit.

Does anyone know if putting fishtails or sharkfin end caps on the 3.5" mufflers will mess up my tune? What about effects on torque and hp? Thanks
