ok i think the headers may have a benefit(in their stock form) for say a mid-mount turbo or extremely high rpm situations where the short runner length and increased primary diameter would allow the exhaust pressure to plenum out so to speak, seeing as the vast majority of the bends are done and the tube straightens out by the collector i think they have promise as adapted long tubes maybe a future offering you guys could manage as all that is required are extension tubes and a new flange to follow along the cat's path. minimal refixturing and a healthy (possibly) bump in the mid to low end curve.

Edit: you could always call them the Stillen headers Gen. 2
