Just wanted some comments as to whether or not they do what they claim (performance gains etc). I've heard one or two good things and one or two bad. Not from any REAL users though....

I installed a set on a 560hp BBC for a friend, two years old, used in brackish water. No issues whatsoever. Great product for the price. Watch for his sales on ebay.

Seemed to run better with them over stock mercruiser, but didn't make any back to back tests, so cant really comment on gains.

I was thinking of installing them on my 454 mags. Just wasn't sure if the Gil's and Eddie's are worth the extra $$! Of course, they say they are because they are more corrosion resistant.

put some on my fountain seemed to run better , sounded alot better, then two months later i sold it wish i would of kept it

i have heard good stuff about the Dana Flow Torques. look like a nice piece and are really resonably priced http://www.danamarineproducts.com/st...FTOKEN=3522819


i did a thread in tech several weeks ago and got a ton of good info

Each marine aftermarket exhaust manifold manufacturer/distributor should have or display the manifold shown as CUT IN HALF or a diagram to show the runner design/set-up within each manufacture's manifold. I don't think many of them do this, but it should be available to the customer. At least it shouldn't be that big of a deal.

The customer should be able to know and see what the differences are internaly of each manifold as it truely is that he may make a better decision before he makes a purchase.

Well aren't the Rev's the old EMI thunder castings?

You know what is really annoying, is when you checkout the advertised prices for the headers, but, then, you have to add for tailpipes, brackets, etc. I almost feel like I'm trying to buy a car!

I considered these, but went w/ Stainless Marine.
I just heard too many good things about stainless, plus i got to speak to BROWNIE!!

I am trying to put exhaust on my 7.4L MPI as we speak as well and what I can't believe is that prices range from $800 all the way up to $2100 and that doesn't even get into headers, just manifold type designs.

I am at the point where if I don't find something used I'm gonna open up 10 different manufacturers websites close my eyes and point to one.
