So I have a 377 rotax in my Amphicat, and I'm looking to quite my exhaust. Can I install dual exhausts, IE remove Y pipe and add two SEPARATE exhausts systems for each cylinder? I can't even find a snow machine with this setup so I need someone that knows engines good to be able to help me with back pressure and flow rates, and your gonna have to dumb it down for me. I read the book for dumbies and got lost :P
