I’m in the process of removing heads on my crusader 454 due to 1 stuck intake valve. When I removed the exhaust system from the riser/elbow, consisting of a combination of 4” marine wet exhaust hose, cast iron 90s, and a cast iron tee. I’m sure it will be fine, but if I’m doing the work, I want to replace with all new. MY question is should I go back with fiberglass instead of cast iron? My last boat had 5.7mpi’s and had fiberglass, not cast iron. What are the pros and cons of each? Thanks in advance!
