This exhaust flang is for making an exhaust system bolt up to a Soltice exhaust manifold with an Ecotek GM motor.If you are going to do the swap ,and make your own pipes this flang will save you a lot of work. It allows for a good fit from the 2 1/2 inch manifold outlet hole to the 2 1/2 inch pipe.Machined out of 1/4 inch plate to give plenty of room for final surfacing.

I am now working on the flang that bolt to the haed.The last time I looked someone sold this item for like $150.My idea is to sell it for about $50.This will allow making your own headers and your own exhaust system.
