so I am now noticing what sounds like vibration coming from the mid section of my Corksport exhaust at idle. It doesnt really look like its moving around all that much but i will be installing kartboy hangers this weekend. The thing is that I'm not sure if this might be an exhaust leak. Is this the typical sound of an exhaust leak? Anyone else have this issue?
