Has Anyone Air Bench Tested the CFM flow of the Dana EX2000 Flow Torque Exhaust Manifold made for the Merc 496? I am looking for those CFM numbers.

Thanks for responding. Can you type the subject line of the thread and the screen name of the original poster in a reply here so I can search it? I would really appreciate it!

Didnt flow it but they are BIG square ports. I think they are 2x2.

Rage

Thanks Keith. Yes I measured them. They are 2x2 for about 4 1/4" until the runners bend up then 2x1.45" for the rest to the collector.

How are the HO 600's running?

Is Dana still making this exhaust? I'm torn between it and the Lightning headers. I wonder if the #5 risers make more power as the water is introduced much further downstream?

I personally type this issue brand of your bond as well as tv screen brand in the first.

I would assume a couple HP if any. I used the 105's and added 6 inches. So they are dry to the tails. The manifolds are good but I am starting to question the type/quality of stainless in the risers.

and rightly so,,friend had/got bad castings,finally leaked water in and almost took out his motor.he got the run around and ended up having to buy new elbows.we'll never use them again.
