lightnings are awesome. I remember back in 93 when I bought two sets direct for BBC's 1150.00 a set. Those days are gone but they are a great header and have a sound of their own. Wish I had the video yet from going through the north channel up in Canada going through the canyon back to the pool (the end) Kinda like a mini Grand Canyon. What a beautiful trip that was.

I don't know of any marine SBC header that won't break the bank. On top of that I have never seen an independent before / after test of performance improvements in a SBC marine application. I would be extremely hesitant about purchasing headers for a marine SBC. I believe the gains are minimal to non-existent, especially with the price factored in.

Hardin makes a SBC manifold with individual runners inside of the manifold and they aren't too expensive.

I have a GLM variant of this exhaust. Made ZIP / ZERO difference in performance. No extra rpm, no extra mph etc.

GLM aluminum manifolds and Imco long dry to transom risers supported my old 383 to 475hp and 80.5 GPS speeds.
