Hooker 3-Bolt Flanged Reducers
Hooker Bolt-on Header reducers use the popular 3-bolt pattern to fit most headers. Simply bolt the collector onto your headers, then weld the exhaust pipe to the reducer.

Oxygen sensor reducers are also available for those of you building headers for a computer controlled car or truck using an oxygen sensor.

A weld on oxygen sensor is even available for fitting to your existing exhaust system.

Choose the reducer by selecting the header collector size, then your exhaust pipe size.

The following reducer sets are sold in pairs.
