looking to get rid of silent chocie off a 99 27' checkmate w/525sc. Would anyone know what type of exhaust (brand name) was used w/ this app. Its a header not manifold type need to replace y pipe so I can sale silent chocie pkg. Also what is a complete silent chocie pkg. worth. Thanks for any help

I believe they used CMI's on the 525sc's in the last year or two of production. Check www.mercruiserparts.com and look up your engine and then go the exhaust. It will give you an exploded diagram.

Why do you want to get rid of those

I wish my boat came with that set up. Noise is not always fun
