been working on my build, bout ready to start putting all cooling tubes and trim tube in, i have my stock exhaust tube that runs under tray through bulk head, I have messed up the flange. option 1 use stock tube and just put it in flush, ive even thought about running it out the side of ski in the rear, option 2 use pvc pipe, unsure bout this cuz im not real sure how hot the exhaust is at that point, with the water in it. option 3 use fiberglass tube or carbon fiber tube not sure if i can find it in that size, any help would b greatly appreciated, im also concerned with the polystyrene foam melting if it is touching exhaust tube.
