It seems louder like my manifolds are going to explode. My heat on/ off assem in the exhaust manifold doesn't spin free so I think I have it set to heat off. Is it a manifold leak ?or Mabey the heat on/ off causing it to sound loud ( sounds like its coming from the engine not the exhaust pipe) if my on off is stuck would it be better to run it on or off? Mostly off? Thanks for any suggestions | | |
