Default NHRA approved tethers. WTF?

I have heard a couple people talking about the tethers, and had no idea what they were talking about. Have not seen anything from NHRA on them.
What's the story?

You mean something like the bikes use, to kill the ignition, in an incident? (tethered to the driver?)

Lokar Header Tether System


Lokar has released a tether system for multi-piece headers and headers with removable collectors/stacks. The Lokar Header Tether System is a secondary retaining device that will ensure the attached collectors will remain attached if the primary retaining device (most often a bolt or tab) fails. The system allows racers to freely and easily change collectors at any time and is universal to fit a variety of applications. The kits are made from high quality stainless, made in the USA, and carry the same lifetime warranty as all Lokar products.
Features
  • T-bolt clamps for ease of installation
  • Works with merge and standard collectors
  • Cut-to-fit tether cable for easy custom installation
  • Stainless hardware
  • NHRA accepted
The Lokar Header Tether System has been accepted by the NHRA for use in all classes and will also meet the requirements for the 2014 NHRA rule change regarding multi-piece headers and removable collectors. From the 2013 NHRA rule book:
2013 NHRA Rule Amendments SECTION 20: General Regulations, Engine: 1,1.3 Exhaust (Page 3) last update 2/4/2013. Effective Jan 1, 2014, removable multi-piece exhaust collectors/stacks must be securely fastened with an NHRA accepted header tether to prevent loss of collector/stacks during competition.
Header Tether System Part Numbers

*Merge collectors must be measured at the valley of the merge



Copyright 2013 - Lokar Performance Products

All products manufactured and assembled in the USA

That's putting it mildly, they're a straight up rip off money grab.

Yup, header collector tethers. Makes me glad my collectors are welded, and that I have exhaust on my cars.

Someone at Lokar knows someone at NHRA....

Someone needs to beat someone at their own game...

I'm sure someone here can come up with a cheaper design that can't be denied approval.

On a properly maintained race car collector bolts don't fall out

Nhra just continues to show everyone what a joke they are.

I drove my car 2000 miles this year and the collectors didn't fall off or the bolt come loose. How many passes would that be?

Or someone from SEMA married someone from Lokar.
