I have two pair of 4" CMI sound eliminator mufflers. They have been used one season, and are like new. I am putting my straight pipes back on, and do not need these anymore.
I paid over $2000 a year ago. I will sell them for $1000. I can't post pics on OSO, but PM me with an email address and I will send you a picture.

What engines did you have in your 382 ? I have 500HP's and they are pretty loud. Are you willing to negotiate on price ?

I used them on 500 HP's and could pass the Wisconsin DNR sound test. WI does not allow switchable exhaust, and they are getting tougher on open pipes. Now that they have all but eliminated the fun from PWC's, they need a new target.......High perf boaters.
These are like new, except for the silicone sealant where they mounted to the transom. They work really nice for keeping you legal. I am going to larger engines and upgrading my entire exhaust system. I paid about $2000 a year ago, make me an offer, or they will have to hit eBay.
