Collecter Tethers?
 

The headers on my stock eliminator car are one piece. However, I use an extension/reducer that bolts to the flange. Am I required to install a tether?

Any information/insight is appreciated,

Good question, I would say yes, seeing you can't have the collector bolted to the pri. pipes with tabs, they have to be stitch welded.You might have to weld the 2 flanges together,making it 1 piece.Give the tech dept. a call.

Now things are getting carried away,
I read that as he has a collector extension bolted to the flange, not the primary tube tabs.
Is this the typical street style 3 bolt flange at the end of a collector?

Re: Collecter Tethers?
 

Can't the bolts on his extensions loosen and fall off like on the primary
tube tabs?:confused:

That's the way I read it.

Your chances are better to win the Powerball, than that happening. lol..

Hope you don't need the 36" tethers instead of the 10", 15" or 20" ones.
They are $50.00 more for an extra 32" of stainless 1/8" cable that sells in bulk for less than .50 cents a foot.
surprisingly the 10", 15" and 20" all cost the same

Yes they can, however, per NHRA we have them jam nutted so that happening is not probable. They are bolted to a street style three bolt flange. My concern is finding a company that makes the rings in which the tethers attach too in a large enough diameter to go around the three inch header and extension. I could make something work, but NHRA is mandating the use of a particular brand that they have approved, thus, making this more problematic.

Welding the two flanges would be the easiest way, but it would make it difficult to remove the headers. It may even make them impossible to remove as I have not tried to remove them with the extensions on.

I wonder if it would be legal to use v-band type flanges and clamps at each junction much like boosted cars run on the hot and cold side of their induction/exhaust systems. Surely with a welded v-band flange and clamp on the end of my collector where it goes into the extension, this would not require a tether - or would it?
