I have seen 427 exhaust risers that are made out of copper. These are designed to replace the standard, block type, CC stock risers but there is an issue. The copper risers only have two VS three ports for coolant lines.
The stock risers have three port and three coolant lines, one from the heat exchanger, one cross over and one that I believe runs to the oil cooler?
I have been told that the copper risers were developed to replace the CC stock iron risers, due to rust out problems, but can anyone tell me why there are fewer ports on the copper risers?
