Info

Just pick the reducer size that matches the diameter of the header collector. Bolt it to the collector ring, and weld on the tailpipe. If you have a header without the collector ring, use Hooker slip-on reducers. They're sized to slip over the collector and weld to the exhaust pipe.

  • Slip-On Reducer
  • One Pair
