These reducers work on most 2 ½” collectors and flanges utilizing the 3 bolt configuration and reduce the pipe size to 2” O.D. They include the gaskets, bolts, washers, and nuts.

The header reducer 2 1/2" part # 91013751 will fit the exhaust manifolds. I have seen some people even run the donut style gaskets with these for a better seal.
