we just got our first batch done and we have already sold a bunch of these, but I am going to hold 3 off for sale in our shop and put them up here for sale instead. These are full stainless with a flex joint, and a machined EGT bung as you can see in the picture. You will still need the factory gaskets for this, or aftermarket, whichever you feel best with using. We have had the prototype on a customers car for almost 2 years with no failure at all and no CELs.
Pricing is $225 + shipping (CA residents add 7.75% sales tax)
let us know if you have any other questions.
