These headers tubes DO install INDIVIDUALLY, and are a slip-fit into each collector. Each rear cyl (#4 and #8 ) 'crosses over' to the opposite side collector, which is thought to increase scavenging by spacing the firing pulses more evenly. Plus, they look like 'a basket of snakes' when the car is viewed from the front (cool). As mentioned earlier, tube dia is 2 inch, and collector dia is 3-1/2 inch with a 3-bolt flange
