Re: Header tether needed?
Also many race style headers are multiple tube, and need to be installed 1 piece at a time. Take a look at the headers on most 390 & 428 Mustangs and Fairlanes. No way to install those headers if they are all 1 piece, (hell, its a major PITA, even with 8 separate tubes!)

Re: Header tether needed?
Not long after the "tether" rule came into effect, at a race in Epping, a guys "tether"
came off.There is even a video of that some where! The next thing will be a "tether" to hold the "tether" on!!! Then a "tether" to hold the "tether" to hold the "tether" .................... Terry K |

Re: Header tether needed?
How long has this "weld-on" tether been accepted?.I thought the reason for using the T-bolt clamp on the pri.pipe and collector was to prevent the old style tabs with 1/4" bolts and lock nuts from breaking off at the weld and the collector coming off.I know you still use the original tabs too, but how is this any better?...gsa612

Re: Header tether needed?
Far from that! Just been a racer a long time in some fast cars and using some common sense. New to the SS game so I'll probably be asking some dumb questions
