I gota a slip on exhaust for my 400 about a month ago. I was wondering if anybody has had any problems with there end cap sounding like it rattling are maken a squeaking noise at certain rpms. I got all three bolts as tight as I think they need to be. I was thinking maybe if a put a thin line of high heat silcone around the inside of the tip and maybe some lock tight on the 3 allen bolts and put it back on if it would make it stop? Anybody have this problem are is just me?

I have a full system HMF and I hear the same thing, I have no clue where it is coming from I actualy think it is the echo sometimes cuz it only really does it when Im getting on it hard..No clue anyone else have an idea?:confused: :confused:

the slip on have a bit more of a raspy sound naturally and the full systems have a deeper tone..I believe the noise is just the air passing through the endcap..just ride!
