Does anyone know where to buy Dutra Duals? What advantage is there to using the stock heat riser on the modified rear portion. I am seriously considering a "Super Six" manifold, which could use the riser. But I might go with the HyperPack style manifold, which would not use the riser. To my eyes, using two of the front sections just looks better, and here in South Texas, I don't need much in the way of COLD weather driveability!

I'm not planning on a /6 SCREAMER, just a sorta "peppy" street machine, so I have been debating the idea of headers. Seems like the ceramic coated headers would overcome most of the durability problems, but I am willing (and HOPING) to be better educated on the subject. My project is a ways away from the build stage, but the knowledge can't come too soon.
Thanks!
