I'd have to say Mr Brown hit the nail directly on the big pink head (see pic), big shock right? Not! Did some research and turns out he's a legend! It's an honor just to get his opinion and advice. I found your "mystery boat info fest" and I've tried to sign up and become a member but registration fails everytime. Pic is from the early 80s and is titled crapshooter 21. As it turns out my seemingly junk "cut up" exhaust is exactly how some of the fastest guys ran them all those years ago, that's extremely cool. Here I was, thinking I needed to replace it. Huge thanks to hydro junkie for going the extra mile for a newbie, people like you are a big part of what makes this hobby great for all of us.
