If you put Drag Pipes on, that is what U should be doing! Other wise you can waste your money putting Vance Hines Drag Pipes on and loose low end torque and will mess up your Gas Mileage. I did fix all of that when I purchased a 2004 HD Springer with those loud ass pipes on it. I bought baffels wrapped them in a heat blanket, or baffle material got 15-20 more miles to the gallon and great long hill pulling without shifting down it the mountains. And if you do your research you can damage your vales running straight pipes.

I'm sorry, I didn;t catch that. What did you say?
