The innovative Thunder & Lightning bolt-on cast aluminum exhaust header boosts your engine's performance 35-100HP! This unique foundry-tough cast tube style header incorporates four individual water jacketed 32" long runners and easily bolts on to most big block Chevy marine engines, including Mercury Bravo, Speedmaster, and Volvo installations.

Anyone by chance have "one" for sale? I can't remember which side but I smoked one of these and am looking for a spare for my other brand new header to make a set.
