" The NHRA Technical Department will also accept a minimum ½” (half inch) stich weld located each primary tube as an alternative to the tethering system."
Don't insult our intelligence with this BS response! Weld my headers onto the car? Only a moron with no knowledge of race cars would suggest this!

This is the craziest part of this rule. "stitch" welding collectors onto primary tubes, (which only a desperate idiot would do) is in no way a permanent solution. It is not a long amount of time before those welds will crack and is
Not a solution at all.
They should also change the "bolt" ruling to say that each tube that goes into a collector have its own bolt and brackets, this would allow for differences with 421 type headers verses 4into1 headers. I understand the ruling is 4 bolts per collector, referring to a normal 4into1 collector?
I am not aware of any foolproof way of keeping headers intact besides a regular maintenance inspection of hardware as it is subject to intense vibration and will fail given enough time. NHRA guys are not going to get under every car and make sure that even their "bolted" retaining devices are still intact.
The whole thing is obviously a attempt to limit exposure to lawsuits and throw them off onto manufacturers instead of those organizations who don't or can't inspect cars they let run on their track or work to protect their "customers" from being hurt at their events.
