[l79Nova]

I have a set of Doug's I was going to use but the shop putting the car together wanted me to run the stock exhaust manifolds to keep my L79 all original. So I found a set that looks brand new. I am also going with Gardner OEM exhaust. If you want a set of Doug Thorley, I can sell you mine. I fit them on the car and they fit good. I never ran the engine. So they are fresh out of the box. They are the ceramic coated Tri-Y headers that fit with a four speed. I do not remember the model as it was a few years ago when I bought them. But it was what everyone was buying. I will sell them for what I paid. $550 plus shipping. They come with gaskets, reducers and bolts. Here is a link to a set online.

If you are having issues with fitment, make sure your engine mounts are correct. There are 2 different sizes and installed the wrong way will make the engine shift over to far on one side.
