I like the take apart design of the Hedmans, but the NHRA collector tether deal S U C K S !!!
If I'm reading the new rule correctly, the hedmans I have don't need the tether. The rule states: Exhaust,collectors,stacks must be securely fastened (i.e.,metal straps,bolted,welded ect) Here is a pic of my W2 1 7/8" to 2" Hedman Hustlers with a 3 1/2" collector which I believe are made exactly the same as the headers you are interested in. Notice the bolt straps on the collectors and every tube that comes apart. The only other problem I could think of is these headers don't work with an oil pan with a bottom kick out. I have a straight sided Stef's oil pan.
