Our mild steel collector slip-on reducers are swaged to accommodate the joining of 2 different tube sizes together and to retain a smooth exhaust flow.These reducers are manufactured from 16 guage mild steel. Collector reducers are fabricated to slip exactly over the selected tube size.
The un-swaged side of the reducer is the OD of the initial tube.
Selected tube size from the drop-down menu will be the ID of the reducer.
