Thanks for the replies guys!!! I went to SPD's website and didn't see that piece of metal that you weld on the inside of the tubes? Does anyone have a pic of what that metal looks like or a link to buy that piece? Also is it safe when i tig the headers up to just fuse them together instead of using welding rod as long as I cut the tubes tight toghether or do i need the rod for strength as the metal expands and contracts from the heat? I looked up to see what the factory LS1 has and they have 1 5/8" primaries and 2 1/2" collectors. Should i stay with factory sizes? I was hoping to run 2 1/2" exhaust. Thanks ahead of time!!
