Mufflers for a 27

[Mario L.]

looking for some suggestions . .

My boat is way too LOUD! 4 x 4" exhaust wide open with twin 383 SBC . ..

I don't want to add external mufflers and would prefer to retain the original backslashed tips, they just look so cool!
So I want to add mufflers internally, I have about 12" of length that I can easily utilize.

Suggestions of what is really effective and works well.

Mario,

Corsa makes tips with the muffler inside. Works pretty well.

Gonna raise those drives up?

I'm considering these for my 383's: http://www.american-hi-tek.com/

They can be fitted inside and you can keep your old tips.

Jeppe,

thanks . . I considered this company when I built my Donzi with the Ford, but working with them in Australia was a challenge. Looks like they now have a USA based sales operation.

Wonder if the mufflers will work with EMI exhaust manifolds ? I can't afford two sets of SS manifolds!

Jeff,
Not likely . unless I can solve the Volvo tilt motor location. Moving my drives up will cause interference on the deck.
I am looking at other options . . . . shortened Volvo mid section.

Right now the focus is on the engines, w/o them I can't use the boat . . .

Allen, the owner of Hi-Tek, ensured me they would fit on my Imco PowerFlow system with 3" risers so I'm sure they can make them fit on your EMI.
