imagine spending $2,800 for one header....

CMI's? Big tube or 525's? I too have a boat and it is stuff like this that makes me want to get out of boating all together. I bought two sets of headers and tailpipes last year and had fitment problems. Mine are CMI's and since I've bought them, I've heard tons of stories about them leaking and hydraulicing engines. Knock on wood, mine are holding up fine. I do only boat in fresh water though.
