Upgrade Stage LevelStage I
I just bought a 2015 street glide special, it has the High Flow Exhaust System. How do I clean the pipes?
Does this system void the factory and extended warranties? So would the street tuner be needed with this upgrade and would that void any warranties?
How much louder is this system compared to stock header and reagular street cannon muffler ?
