Pure Stock Open Headers
 

I really love the Pure Stock class. Even though I am building a "new traditional stocker" , which I guess have turned into 9" Super Stockers, this class just brings me back to when my brother Ed and Joe Huestis built a 69 Nova they ran in V/SA in the 80's "cheater cams, stock springs, ect.

The only thing I don't like is why not let them run open headers, maybe that would be the beginning of that "slippery slope" , which might have started with the cam rule.
Just my .02

No need for change on that one

If you want to run open exhaust, then run the factory exhaust manifolds.

And even though you can't run "straight-through" type mufflers, with the advance of larger diameter pipes, removing cats (on late-model cars) and race mufflers I think you can still stay within the rules and still not lose that much over open headers. I'm not so sure that some of the combinations don't like a little back pressure and although we've never tested it I wouldn't see our Pure Stocker picking up much completely uncorked. Some of new mufflers sound really good too!
