I talked to H-D Customer Service on installing Touring Screamin Eagles(myself no remapping or different air intake) on my 02 FLHTCI and warranty issues. They told me as long as I used the Touring style H-D slip ons that my warranty would still be valid. The dealer told me just the opposite,that if I installed them I would void the warranty. He also wanted $800.00 for the above system and they would stand behind the warranty. Has anyone had any experiences like this?
