I personally havent yet. However, pm pm203, as he has the same setup and to my knowledge has not been bothered by the lake winni police.

HPIs are still in business. GGB went out and that is a shame. They made a great muffler. Dont go with ZOOMERS.

I installed a new set of transom mount GGB's - only ran them on the hose so far (will be splashing the boat this Sat. for the season), made a HUGE difference in sound reduction. And before you ask, it was the last new set out there

, they are out of business.

We also have had great results with the IMCO Gattlings.....great sound at less than 89db.....and the inserts cannot be seen like the add on tips on the market.
