I'll be testing IMCO Gatlings on Merc 700's this Fri, 5 inch tips

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

Why ??? ...i have a set ...and want to know what is the problem ??? ....thank`s in advance ...i don`t know if he past the db test ??? ... look here my set up ..... i love the sound

My HPIs were tested at 92 dbs with Merc 500s.

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.

Just got back from Havasu, Twin 700 Mercs, 5 inch tails with removable IMCO Gatlings,,,90db

bootfeeder,
What was the db reading without?
