Free to a good home - 2000 382 Silent Thunder box
 

I took it off years ago, and it's just sitting around. It has no cracks and still has the oval-shaped rubber flappers. Come get it in Port Deposit Maryland or pay shipping, and it's yours!

I'd hold onto it if I was you.
With so many states enacting noise level laws you just may need to reistall it to stay legal. Or spend big dollars for mufflers.

Dude, you have no idea of the engineering hanging behind Chuck's Formula :D


Come on Chuck, got any recent pics of your muffler setup :p

These are quieter - and do NOT fall off.....

Hey Chuck, I still have to deal with the ya-hoo's up in Grand Haven on exhaust issue. I've got until 6/15 to demonstrate I've corrected db. Mulling over options which include doing nothing. 496's w/ silent choice.
I have wondered about the silent thunder and if I should consider it. It appears my boat had it at one time.
Do you think your 382 box would fit my 353?

I have the ST that i took off my 303 SR-1 if intrested.

Some pics

I have the same thing off a 1998 312 in Cincinnati if anyone can use it.

I have a 353 box complete and nice. it was on my boat 1 season.

What's wrong with Silent Thunder?
 

Judging from other posts it seems like a lot of people are removing ST. I am happy with my Capt's Choice but it really cuts top speed and I assume fuel economy. I was thinking of installing ST for the lakes and rivers around here, but I am wondering if that is wise.
