For thos who have not heard the NHRA has ammended it's tehter rule for 2014. Here is the latest version of the rule. Basically if you dont want to run one of the NHRA approved tethers from the two approved vendors you can simply have a 1/2" stitch weld to each primary tube. I am sure there will be more changes as it gets closer to next year. Here is the link http://www.nhraracer.com/content/general.asp?articleid=56756&zoneid=132

Yes tabs and bolts as of 2014 will NOT be legal. You will either need one of the two excessively priced NHRA approved tether systems or as amended a one inch stich weld on ALL the primary tubes. Results of racers NOT doing maintenance on their cars and causing injury to others.
I have tabs, bolts and mufflers and still have to conform to the new rule.

A buttload of cash!!
And a jar of that special petroleum jelly
I'm all for being safe and the safety of everyone else. If they are going to check for tethers on my headers, why can't they just look to make sure my tabs are bolted properly?
Maybe they should have sealed lug nuts
Once they are torqued you can not remove them without the express written permission of the NHRA

What's the ruling if the car has pipes and mufflers on it?
The way the rule still currently reads is if you have a slip on collector you have to either stitch weld or purchase the approved tethers. Since I have mufflers that was why I asked and that was the answer I was given last week.
yea cause we all know welds on headers never crack
nhra...gotta love em

I have been depressed for over 2 years that I had to sell my ride BUT the more crap that comes out like this the better I feel about it. When I do get to go back to racing it will most likely be on a bike very little safety stuff there to worry about. no belt issue no net no ect ect.

I will be asking again this next weekend at the Salt Lake divisional if my stuff still needs the tethers. My guess is the answer will be yes//Oh yeah I got caught up in the whole window net deal as well. Since they had not amended the rule before the Phoenix divisional, first race of the year I was forced to buy a new net. So there went $150..Imagine will get hosed in this deal too since I doubt they will have clarity before Pomona again.

I have an A Body that has 8 different pieces to put my headers on. I wonder if I will need to tether all of them lolol.
This is realy getting out of control... Next thing they want you to do is tether the drive shaft...
I was just thinking about headers built this way and people changing their current headers to utilize slip tubes a few inches away from a welded collector. The way the rules read, you could weld the ends of the primaries to the collectors and have slip joints a few inches away from there with tabs and bolts. I hope headers companies are considering redesigning some of their current systems to utilize something like that.
Weather you have a short piece welded to the primary and then have a bolt on extension its all considered collector...... my way of thinking... DONT GO TO ANY NHRA RACES... let them see what happens over 1 year.. they WILL be crying the blues... this is getting WAY out of hand... I havent seen it in the IHRA rules

I have seen collector extensions come off, but never saw the actual collector it's self come off,,if it was bolted properly with tabs etc. If welding is not acceptable at the collector, why is welding OK at the flange area at the head?? Maybe NHRA should tell the header manufactures to tether them there too. I have bolt on header extensions on my TTI headers. I will put tapered loc nuts on them with loc-tite, lock washers and drill the bolt for a cotter pin. Suppose that will pass??
If you like drag racing, support your local track.

I find this whole rule stupid. Its ok if the collector falls off, just make sure you catch it. How about don't let it fall off in the first place. Lock wire your bolts, lock wire your tabs, use a cotter key to secure nuts, something, just don't let it fall off in the first place. I don't think anybody is debating the danger, so inspect, not for a tether, but for a sure method of securing in the first place, eh?
