What's the thinking on high-flow mnifolds (like the rm horns) vs. long tube heders (I guess like the Throley tri-Y's). The thorleys are something like $500, but they are extra thick nd gurnteed forever I believe. The ram horns just plain look cool and will last longer longer than I'll be walking the earth. I'd be putting these eventully on 383 Vortec. -- Mike <font color=blue> The mud's on it to hide that it's more than one color.
