Muffler removal, straight exhaust
2001 Mobius. I have a muffler leak and have read of all the problems other owners have had with the fiberglass mufflers. I'm considering the removal of the mufflers and replacing them with a straight exhaust tube. No leaks and it's simple.
I don't see any problems with getting water into the engine.
I'm not sure how loud it will be. Any feedback?
I don't think the engine performance will be affected. The long tube and exhaust below the water line should provide sufficient back pressure....?
Any advice is appreciated.

mufflers dont really provide much back pressure anyways and if you want performance you dont want back pressure. the straight exhaust will make cruising very loud tho

Makes me think of the big chrome pipes off drag boats. Once your boat is moving fast enough so that the exhaust outlets are above the water line I'll bet the droaning roar behind it would be mind numbing...
So when is this "old enough to know better" supposed to kick in?

I think it's funny that someone is worried about exhaust noise when my daughters have the entire boat shaking to the rap crap coming out of the speakers. It might be good to know the engine is still running.....lol
