This is the core of what we do at Morrison Fabrications.
321 stainless is now the standard material for all of our turbo manifolds!
We’ve been eyeing up 321 for many years and were really excited to find a solid supplier to make the switch. While 304L works very well (and has been/still is the standard manifold material used across the board), 321 is a stabilized grade of stainless that has much more ideal high temperature properties for a turbo manifold.
Pricing will remain the same despite the higher cost. For the immense amount of time and effort that goes into the development of each manifold, we feel really good about building it from a superior alloy.
A high quality product made with some of the highest quality material.
