Hooker Headers

We installed the Hooker 1 7/8-inch headers that we will use in Mark's GMC. We were surprised that they actually made a little more power than Don's dyno headers. Most times Don's customers' test headers loose power against his monster dyno headers. We feel that this engine better reflects the design of the headers. It's not often that we see a slight improvement with the headers we will run in the chassis.
