Hi guys, I'm new to the forum here and new to superjets this is my first one. I bought it used recently it's a 96 and it runs well, just was wondering if the cooling routing is correct? I'm just wondering why it's blocked off at the top of the pipe? Is there another place it goes in? And also there's a small hole maybe a 1/4" or smaller under my exhaust outlet has anyone ever seen this or have this? Is it supposed to be there? Any help would be greatly appreciated thanks.
