        No need for RTV with these

        These will last forever. They have a nice steel core and even held most of their shape when I had to takle them off and re-bolt them up again. I will use BBK gaskets anywhere I can from now on! The gaskets that I replaced only had 3K miles on them, but they were already leaking, even with a layer of copper RTV on each side. I'm sure that these will hold up far longer.

        Header gasket

        The header gasket was a major deal to complete my order in purchasing the header. The fitment was accurate, the headers were accurate and the product that American muscle providers is just wonderful and I will definitely purchase again.

        3.8 V6 Header Gaskets

        These gaskets are a sturdy, high quality steel core design and a bit thicker than stock. They are relatively easy to install even within the cramped space under the hood of an SN95. So far they have provided a leak-free seal on the high-mileage factory aluminum heads. If needed, would definitely buy again.

        The header gaskets for my 01 v6 mustang fit perfect. Way more durable then the ones they came with. Great buy!

        I bought the BBK shorty headers awhile back and used the gaskets that came with them. About a year and a half later the passenger side gasket blew out the back and gave me an exhaust leak. Took me forever to find it since it was on the back of the header. I ordered these gaskets and installed them with ease. Running smooth now without a loud exhaust leak and couldn’t be happier. Thanks American Muscle!

        Didn't last

        Bought these gaskets to go along with my MAC long tube headers and the gaskets only lasted about 2 months. Little pieces started to come off while it was installed and now I have an exhaust leak. Not sure if I got a faulty set, but I won't be able to tell unless I get another pair.

        Not needed

        Information on the website and along with the header order led me to believe I needed to order these gaskets. They arrived like 5 days after my headers which actually came with gaskets. So I will be returning these. I'm sure they are nice but didn't need them hence the one star rating.

      Is the diameter 1-5/8 {1.625} for these gaskets or are they the oem 1-1/2 {1.5}? I am looking for 1-5/8 {1.625}.

      • These gaskets are 1 -1/2 inches, same as the OEM, unfortunately, we do not carry an exhaust gasket that is 1-5/8".
