>> Today, I had to tighten the 6 nuts on my exhaust down pipes.  This is the second time in 2 years I have had to do this.  What is causing the nuts to work loose?  Each of the 6 studs from the exhaust manifolds has split lock washers and brass nuts on the down pipe flanges.  Each time time I have tightened the nuts, I tighten them until the nuts squeak.
