Spectre's Header-Collector Reducer kit includes two 3 to 2 1/2 inch header reducers and a set of extra thick 1/8 inch gaskets. The header-collector reducers are nickel plated for a long lasting, great looking finish. These header-collector reducers also have a 3-bolt welded on flange with a 2-1/2 inch reducer pipe to allow you to attach a 2-1/2 inch pipe to a 3 inch flange. The gaskets are compressed of ceramic fiber (CCF), which is designed to exceed typical non-asbestos type gaskets.
