I'm sure it's been hashed out many times but I have a 2008 ultra classic with high flow air kit and screamin eagle slip-ons. I had the computer remapped. I am looking for some true dials to replace the slip-ons. What are the best for looks, sound and performance? I noticed the rh coming out of the rear jug are close to the frame. Are there any centered in that area? Just lookin for opinions and I know everyone has there preferences but why?
