Honda atc 110 exhaust

[Zachary Edward Shea]

So I just bought an 84 atc 110 and I noticed its almost got a whistle to it when you ride, I did look down the exhaust( don't get me wrong I know its not turbocharged im not an idiot) and it looked a propeller in the pipe letting air pass through. is that just the old baffle or something else?

I think that's just how they are. I had a 77 ATC 90 that had a homemade exhaust one it so one day I came across an ATC110 exhaust on craigslist and it bolted right up. It made a whistling sound. Not sure if it's normal but it ran great.
