I bet!!!!: When the engineers came up with the SuperSix idea, they wanted to enlarge the exh. man. for the bigger exh. pipe, and the bean counters said "NO way Jose!" LOL
But just look how easy it is for a redneck doofus to do. Imagine how easy it would have been for them. Heck, I'd love to have seen an HP exhaust manifold...or even a split like the Hyper Pak. But oh well.
