Hi Guys, My boat does not have any exhaust tips for the through haul. You can see my pic, just has the flaps and the other blue one same as mine does not. Is there any harm adding these to mine? If Not, where is the best place to get these. I cant seem to post the pics, but you can see the blue one in the link. http://www.offshoreonly.com/forums/g...questions.html This one is not Not mine.
