If you have a Pontiac in Australia and it is an original right hand drive made car you will know that you cannot buy extractors for the V8 motors. As we wanted performance for the 1957 Superchief and the original manifolds were holding it back Shane decided to custom make mandrel bent Stainless Steel extractors, going from 1Inch 7/8 primaries to 2/1/2 inch pipe. Letting the 340 breath added significantly more power and increased the economy as well. He then finished this off with a Stainless Steel Mandrel Bent dual exhaust system for the 57 Superchief as well.
