Description
Application Table
 
Replace your old worn or damaged exhaust nuts with a classy new looking part!

Use an exhaust nut wrench to loosen and tighten these nuts otherwise you may damage the fins - see Part No EXNut-Wrench758

Do NOT install new nut without first applying copper (not silver) anti-seize on the thread - see our Part No:
LOC38650.
NOTE: Exhaust nuts must be spun off every 10,000 miles during a major service for application of antiseize.


When struggling to remove seized nuts, heat them up to 300degF to loosen them.

In extreme cases you may have to cut the nut off being careful not to damaged the thread on the cylinder head.The nut can be cut off with a hack saw or dremel. Cut the nut and only saw down "to the threads" of the head. Now hit a chisel in the cut to try separate the two pieces. If this does not work, then make a second cut on the opposite side of the and use the chisel to separate the nut from the cylinder head.
