Exhaust collectors/stacks must be securely fastened (i.e., metal connector
straps, bolted, welded, etc.) to prevent loss of collector/stacks during competition.
Effective Jan. 1, 2014, removable multi-piece exhaust collectors/stacks must be
securely fastened with an NHRA accepted header tether, such as Lokar’s
1400009 or 1401009 to prevent loss of collector/stacks during competition.

So even if the collector is strapped, bolted or welded to prevent loss a teather is still required. Certainly makes a lot of sense to me.....NOT!

What a joke! It BOLTS on. So their "Approved" bolts are more secure than your bolts.

No kidding. Typical overreaction .
How about "Two welded tabs or straps on each collector, 1/4 -20 bolts, lock washers required"
Then have a tech get down on the ground and look under the backside with a mirror.
I know. "fat" chance of that happening...(Not you, Travis)

So this "tether" will keep any loose exhaust tubing "contained" under your car, potentially bouncing around and beating on your fuel/trans lines, oil/trans pan and/or the driveshaft?:confused:

I also wonder if this has any affect on cars using full exhaust systems, with or without mufflers.
