I have a 1987 Supra SunSport (351). The boat came with SuperTrapp disc mufflers. I have seen these on many of the older boats pictured here on the forum.
What are the pros/cons of these mufflers (other than making the boat louder, which is a con in my book)? I pulled them off and ran the boat and didn't notice any performance difference, except that it seemed to run a little rich.
Before I remove the whole assembly -- which is no small task given the amount of adhesive caulk they used -- is there anything else I should consider?
