Last month on "Trucks" during truck gear they advertised "Header Hush". It is pieces of metal about an inch thick that you basically replace the flanges of your collector and header with. I ordered a set because the headers on my k5 are cheap anl leak more than anything else. Man, NO MORE LEAKS!! If you are frustrated with your current situation with your headers and do not feel like buying a new set, then check these things out.
