Let your Pro Stock car breathe.
If you're building or upgrading a Pro Stocker, you need to look at Dynatech's Pro Stock headers. They have equal-length primaries to give exhaust gases the straightest, longest run possible out of the ports and into the primaries before they encounter any bends. These headers have CNC laser-machined flanges with raised ports for increased power, port gussets to eliminate cracking, and jig-located mounting tabs for the collectors.
