This is the second kit I bought from Speedway. Really nice to use. The first kit I made headers for Dog Spit. The second kit, I made headers for the 261 in the Bantam so I only used the drivers side. The pipes are 1 5/8", there are two collectors, two flanges and gaskets for a Ford 289. I got my value out of this. If anyone can use the other parts, they are yours free. Just figure the shipping or pickup.
