Suzuki C90 Slip on Mufflers
 

I just bought a pair of Roadhouse 65 slip on pipes for my bike. Does anyone know if I need to do anything other that just mount them or do i need additional modifications to protect my engine? A local dealer said just adding the pipes should not damage my bike. A Vulcan rider with fuel injection also said it would damage my bike.

a little confused!

thanks,
