Doing a BBC engine install my son and I needed a set of header reducers to finish the exhaust. The pair of reducers came with everything necessary for the installation. Can't believe how well they fit for the price. Would buy again in a heart beat. Fast shipping too!!

Exactly as listed.

It was my fault but i thought they were 3 inch to 2 1/2 inch. Most headers out there have a 3 inch collector. I mistakenly ordered these because the price was great, and missed the fact that it says 3 1/2 while ordering quickly..but i cant use them because i have 3 inch header collectors. Its not worth shipping back so ill keep them and use them for a future project.
