Yes, they are Hookers for an 86-87 Buick turbo. The crossover joins both headers together and then a seperate pipe comes off that to the turbo. They're know for causing a really slow spool and are better for high HP cars rather than stock ones. There are 4 pieces to the set up and he's not showing the cross over or the up pipe to the turbo. As they are they make great NA headers and with the crossover you can make a killer single shot NA system out of them.
