Hey guys, I've been chasing down a chirping noise coming from my exhaust. Have Vance and Hines true duals. Removed mufflers and crossover leaving just the two head pipes. Chirping is still there. Sprayed wd-40 on front heim joint. Chirping is still there. Three different exhaust gaskets, still chirps at that rpm. Even put the stock head pipe only and Oem tapered gaskets back on and it still has that chirp. I'm missing something. Any other ideas where to look?

 

is there a birds nest present?

 

never mind.

 

My Franklin aircooled had that chirp. Leaking head gasket in that case.

 

Did you try holding the mufflers to see if chirping stops, it's possible the rubber mount hangers are dried up and making the noise. Also holding and letting go the front brake should make difference in the noise and if it does you have something loose or rubbing against something to create that noise.
