Slow down, son, you'll burn somebody!

Click and Clack this weekend and they were saying holes in the muffler
could cause the valves to burn due to not enough back pressure

euro headers and euro exhaust system. I did not adjust the fuel mixture.
Later that night, out on the highway north Albany NY I burned a valve. I
had always chalked it up to a possible lean mixture with improved
breathing that burned my valve.

I write:  So if someone is considering headers, or freer flowing
entrails out the back, what would he or she do?
