Very well said.....

It is a little muddy. My understanding all along was the tether itself should be minimum 1/8 SS cable, and a loop of some kind on each end secured on a primary tube and the collector with a T-Clamp (Aircraft Clamp and several other names). Or you could have used a tether with a loop on each end, the collector end secured by the T-Clamp and you could bolt the other end to the frame with a bolt thru the frame. I have sent this to NHRA thru SRAC for clarification. Sometime what they mean and what gets printed is different. There seems to be confusion on the multi piece exhaust that run all over the car like plumbing pipe which I think some Fords got.

NHRA is requiring 2 methods of retention if you headers have removable collectors. Conventional method plus one of 3 options.

This is what I was going to use as a secondary option #3,but the clarification is so vague!.

Dan, I don't think it's the cost of the parts (though it may be in some cases) needed that has most scratching their heads. I believe it's the apparent vagueness of the wording and the revising that has most wondering...my self included. Heck less than 100 dollars and you're sweet, but again why put it on if the NHRA is just gonna rescind it or change it again. Merely my opinion. Joe

Per NHRA. Three methods of retention. Collector welded to primary tubes; approved tether, or hanger attached to body and collector so it can't fly off. I think all the details have already been talked about. The third option (hanger) is the newest. I think it is worded badly, but they want something bolted or attached to the body so it can't be removed very easy. I think we all knew about the welding and the tethers. I think Dan is right; it's just not that big a deal and it's once only. I am the messenger only.

What I do know is that the Collector Tethers that I ordered came on time and fit perfectly. Fitting perfectly might not sound like much, but I had very specific dimensions with no real margin for error. Moreover, I took them on an airplane with me to Cali, so if they were wrong I was pretty much screwed.

I think this has been the most overblown deal I've ever seen. It's not like they're saying you have to buy new ones every 2 years, it's a one time deal. Mufflers were worth fighting about, this is not, IMO.
I'm surprised they let you through security with those, Dan! Lol!

After all of these years I'm going to have to change the strap steel and bolt's that came with the Headers ? Nothing has ever fallen off ! With 2 straps on each collector bolted front and rear, what do I have to add to make them Happy ? Tethers ? I'm old bear with me !...John

I was walking through the staging lanes when Super Comp was staged....Apparently they do not have to have header teathers....Very few, I would say one in ten, have teathers. Guess rules are different for different classes. Please note, I did not see any collectors on any super comp cars that were not secured properly.....I'm just saying....no teathers.

Were they welded ?

I am down to crunch time trying to finish my wagon. Our chevelle needs a set of tethers. I don't like be hassled in tech therefore I try and do as I am told.
I called Scott with collector tethers last night 7 o'clock my time. He took my measurements. I will have a set waiting on me in South Georgia I really appreciate him. There's nothing better than a company makin sure you get your stuff.
If you are on the fence still like I was and don't want no hassles collector tethers can eliminate that.

What Rick asked....were the collectors welded to the primary tubes? If so they don't require tethers, if they just had the interfacing tabs with bolts/nuts or springs I'd love to know how D7 is so different than everywhere else (geography excluded of course)??

we'll have a few extra sets of tethers with us at Valdosta if anyone need them.
