Doug, I don't recall seeing anything about weight of your manifolds. I'm wondering if there's any weight savings, using both Dutra front and rear, as compared to stock exhaust manifold.

Should weigh slightly more than a stock manifold I am guessing. Since it has another exhaust outlit casted on to the manifold. Im thinking around 5 pounds more sound right? But with benifit from opening up the exhaust I would think the added wieght is no biggie?

I also have a question on how it sounds Doug. A guy at a local show told me it sounds great gives the 6 a nice clapping sound just like an 8. Is this true? Right now I am running a stock exhaust manifold going into a Y splitter to create dual exhaust with 2 glass pack mufflers. It sounds nice and deep but more like a drone sound. I am looking for more of a clapping sound.

SO anyone got an extra set for sale?

Truth is that these are thick-wall and pretty heavy, 16 lbs each last time I checked. Needless to say that I wanted my manifolds to last longer then the SL6 engine itself!

I have a Dutra casting on the front three cylinders, and a modified stock manifold on the rear three. I don't know how much the weight of the Dutra casting is, if its more or less than the modified factory manifol, but I don't think its a big difference. I think the Dutra casting would flow a litle better. I've been thinking of getting another Dutra casting for the rear three cylinders of my slant. The modified factory manifold is okay, but honestly, I think a pair of Dutra manifolds would look cooler. I would lose carb heat, but here in Texas, its hot most of the time. I'll post if and when I get a second Dutra manifold.
