Hey everyone, I'm still undecided about what exhaust to go to when I get my bike (2010 ultra) this fall or next spring. My buddy has an 02 ultra with samson ovals and I really like the deep throaty rumble to them. Question... he said when he installed them that he could look right through them, does that mean there is not a baffle in them? From what I have read these bikes need a baffle for back pressure and all around better performance. What size baffle should the pipes have? Thanks for the help.
