JDL UEL headers used for about 4500 miles total. I've had them for 2000, previous owner 2500. Sounds incredible and seals perfectly. No exhaust leaks.
The titanium thermal coating means that no heat wrap will be needed. Heat wrap is usually needed for most other headers (tomei and the similar).
Small amount of thermal coating wear on the underside. I bought them that way, and there have been no problems. No more wear has developed since my use. Can be easily recoated or left as is without issues.
