Banks is CARB certified. Also, Banks headers install with NO manifold gaskets, just like the factory manifolds. The other brands, with thinner flanges, require gaskets to seal.
I suspect Dug Thorley and Gibson is also CARB certified.
The performance gain on the old 460, with headers, is impressive.
My Banks 460 headers have been flawless for 13 years.
