Was going to change out exhaust manifolds on twin 502 MPI's. Anybody have anything good or bad for EMI thunder exhaust?

I ran them for 1 season, I think they are a nice upgrade from stock manifolds, quite a bit lighter anyway, they sound nice, they are by no means top of the line, but a good bang for the buck My .02

The customers i have sold them to have no complaints. They have a five year warranty.

I had a 38 Baja with twin 502 MPI's. I went with the Eddie Marine manifolds and had no issues for 3 years. I then sold boat and they are still on them now going on 5 years.

I prefer Dana's. They are less money also!

I assume CMI's are the best.

You are correct . . .not that I'm biased or anything!!

We can get you Unitops at very close to manifold pricing...

A true header with awesome looks and great performance. They will replace any exhaust as long as you have a standard bravo exhaust set up.

Ran them for 4 years in fresh water single BBC app.

They look like a Gil copy .

I had EMIs on my last boat. No problems with them at all.
