For my 81 Malibu with a L31 350 SBC (street driven) I have purchased a set of Schoenfeld Headers, # 186-3. The collectors on these headers are smooth round and do not have a flange on them. I want to use these headers with exhaust pipes/mufflers. I am thinking I need a 3" flange: Patriot Exhaust Collector Reducer 3" Collector Diameter, Part Number: 737-H7237, from Jegs.
Is this the solution?
