I saw the fresh air exhaust and thought Hmmmmm. So I welded one up for me. They say that it reduced the exhaust noise by 50-75%..............Wrong. Not for our boats. You ready for this, I can't even hear the exhaust at all now. Literally. I surffed behind it the first time I put it on and all I could hear was the wave. It is pretty noisy that wave. but the bbrrrrrrrrrrrrrrrrrrrrrrrr is gone. Some of you may think "he might hit somthing with it, " yup I could but i'm going to take out the prop and rudder first. I am not too worried about it. The fresh air exhaust has a flip up, but thats ok. It does flip up water onto the swim deck at high speeds but wakeboarding and surfing is all good.
I LOVE IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
