I have it on my boat - best thing you can do for your boat! less fumes, less engine noise. You will be amazed at what a difference it will make. Here are photos on my sanger v215 http://www.sangernation.com/index.ph...viewthread/15/
i broke down and bought one this year. i was skeptical about it. im very impressed with the engine noise reduction. we were out couple of weeks ago and i was trying to teach a guy to surf from the drivers seat....... we were able to talk back adn forth without screaming. i bought it mainly for the noise. i never really noticed a lot of fumes from my boat but i do notice a reduction there also. all in all............ very good product. took me about an hour to 1.5 to install.
Just bought one and love it. I wish I had bought one when I first got my boat. The reduction of exhaust noise is my favorite part a the owner of the company is great to deal with.
