Header Tether Requirement Clarification

[Rich67stang]

This has to be the most ridiculous rule needed. If your header collectors blow off because your tabs are rusted/rotted and you do not maintain your equipment, but adding tethers solves the problem...unbelievable.

NHRA says a 1" stitch weld required on each tube, in this case the collector is one-tube and the extension is the other. That is how I am understanding it.

Got that answer from one of the vendor about welding the extension...well..got a few weeks before 1st race.
