Totally understand, I just see too many "stockers" pick up from a well-designed X pipe set up. I too am rocking stock manifolds on my 72', I have a mandrel bent 2.5 system with an X crossover. I don't expect it to be mind numbing fast, just trying to eek out every last bit without headers, a radical cam, aftermarket heads & intake manifold, etc, etc...
