Cornflakes. I will ask Steve my fabber to see if he will do this. The problem with stainless steel is its thermal expansion properties.
Just as a reference stainless steel expands 50% more under turbo heat temps than mild steel. Expansion then has to be considered in the design. Longer runners will be needed and all welding will have to take the expansion properties of SS in order to have a stainless steel turbo manifold to last atleast 10,000 miles.
This is why we do not use SS and mild steel.
I understand the bling of stainless is purty. I love the look too. When selling something that has to go thru the demanding rigors like a turbo manifold, reliabilty has to take precedence over form and beauty.
Regardless I will check tommorow for you. But I will not provide a 1 year warranty on the SS manifold if I decide to do it.
