Had the Thunder Monsters off and tried the Quiet baffles in my Vance and Hines BS.
Went to install the T.M. and forgot which end goes into the pipe.
Is the washer gizmo towards the end of the pipe?????
I threw the directions away (but hey guys, I did READ them ). From what I could remember, they said they could go in either way and recommended that you try both ways to see which setup you preferred (are they supposed to sound different, dunno). Anyway, I just put them in with the bolt type thing closest to the end of the exhaust pipe and left them that way. I really like the way they made my bike sound. Loud, but with a deep rumble.
