Hi guys. Ive got a question regarding my exhaust on my 88 5.0L lx. Other than the exhaust manifold gaskets, are there any gasket used at either ends of the H pipe? Im taking out my mac stubbie equal lenght headers and im not sure if i need to put gaskets at the collectors on the h pipe or not. The mac didnt need them due to the design and im not sure if the stock headers came with them or not. Thanks in advance for the help. Ron
