Is anybody using these? and what has your experience been. I have an Outerlimits with 900SC's, and Stelling Big Tube Exhaust and would like to install these. My friend has them in a Top Gun with 1050 HP Quad Whiplle motors and they sound good and very quiet almost to quiet.

I have had them for about a year. Very nice product. Would definitely get them again for the next boat over the others I've seen. No power loss at all after installed and a cleaner transom due to the extension of the tips. They make a permanent mount and a clamp over your existing tips.
