Ivan.....I assume you boat in Salt being from NYC. If I am not mistaken isn't water intrusion through exhaust rotting and weld fatiuge the biggest cause of engine failures in salt water boats? Thinking someone can put together "safe" marine exhaust for $350 is comical at best. I won't even run used exhaust on my boats, unless I am 100 percent sure of the history since new, and even then I would have them checked out.

Sure, true headers new are expensive......but not nearly as expensive as the engines they are attached to in most cases. Headers add bling, give better access for repairs, and give a slightly raspier "true header" sound that many can't even discern. In most cases a SM, GIL or similar will give the same performance, and are much safer overall due to their simple design. However, the cast aluminum manifolds of SM, GIL and such are far from salt proof.

also the alloy in these headers is not the best for a corrosive environment.

I'm all in favor of buying good quality items from any country/market..even from a little green man from Pluto- it doesn't matter- but sometimes spending more on the front end can save a lot on the flip side. I remember an old saying

You can buy new oats or the ones that have gone thru the horse -- those come a little cheaper!

After seeing this video I cant believe that headers don't fail all the time. Manifolds seem to be the most durable construction.

For some ,the quality lives on long after the price is forgotten
for others , the dissapointment of poor build quality lives on long after the joy of a good deal is forgotten

If your 33 baja has 2 motors and you moved into hp500 cam grind specs your about to spend 2000 dollars on 2 used gil mani-riser combos minimum. .stock mags looks like alum 496 system is bang for the buck . 540 strokers that still have a rumpity rump from new cams ,better brace yourself . You thought the motor builds were expensive .

Prev post wasnt aimed at you btw ,i was just adding to 3pointstars colorful alalagy

I think the OP already realizes that those headers are junk once he realized they aren't even water jacketed!

Is that one header in the video loose?

Wtf. Kinda interesting to say the least.
