As stated in the title these are freshly ported front and rear manifolds off of my 96 riviera. I heat coated them with dhp high heat black paint, heat wraped them with dhp 1" heat wrap, secured them with dhp stainless zip ties, and finished them up with dhp sealer on the outside of the heat wrap. Reason for possible sale would be because i am looking at some headers. Any questions just ask. I am taking offers currently.
