Two Brothers

I just bought a use set of Two Brothers pipes, going to install them on my 99 Std. My question is do I use new OEM gaskets or will I need the gaskets for these pipes. 
Thanks Joe

New OEM

OEM copper gaskets. Squeeze them down a little bit before installing the pipes. The nuts will get a better bite on the stud threads when you do this!
