GGB muffler inserts
Posted: Mon Jan 30, 2017 5:39 pm
The 318's on my 1988 28" M express seem to be getting louder under the hardtop. I thought about replacing the veritone mufflers but looks way to difficult to access them, probably lifting the deck to do the job right. I found these as an alternative, GGB Inserts, they are attached SS rings that are inserted into the transom exhaust tube, not supposed to create back pressure or lower efficiency. I called the manufacturer in Canada to get size recommendations and after a long phone conversation I am quite confident they will work and ordered a set. I will report on the inserts after the spring launch. Anyone with experience on these inserts or comments welcomed.
