Just put my HPx hard line on today from riffraff, i also noticed a difference in noise and idle quality. Cheap and very easy mod, well worth the money.
The hard line goes in really easy too. Just slide it in from the passenger side, i didn't have to remove anything but the two plugs.
^^^ agree. I was very surprised by how much smoother and quieter the engine is. I got the same HPX, very easy install. Even the factory plugs came out nice and easy.
