A good 5-point bolt and nut can be better than a metal weak weld from contamination or not enough penetration. Greasing the palms of those sipping fine brandy under palm trees. Go figure.

This is realy getting out of control... Next thing they want you to do is tether the drive shaft... Just One Man's Opinion Mopar Mafia Racing

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. Last edited by Adrielp; 09/19/13 09:30 AM.

I've used common sense when putting together my collectors/headers/muffler and will make a stink about it when I get told by tech to make a change to them.. until then, I'm not going to worry about it.. 73 Duster 360 stroker http://www.cardomain.com/ride/2594657

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 am not ashamed to confess I am ignorant of what I do not know."

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

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.

They are custom built. I guess i'll have to cut welds everytime i have to take them off. That's bullsh-t. Maybe i won't go to the races anymore.

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?
