I am not sure I understand what you are getting at here. Are you considering an "upgrade" to the cat exhaust? As far as I know the cat exhaust was required by EPA regulations and it wasn't done for a performance reason. Maybe I have that wrong so I'll be interested in responses to your post.

The introduction of cats on marine motors was an 07 EPA mandate and are the stock manifolds for an 08. I believe the only motor that didn't get them in 07 was the 8.1.

Welcome to the 40th Anniv family!!!

In 2008 the CATS were on the 197's and some people took issue with the added noise level that was produced so I believe for a little while MC was working with owners to add mufflers to help dampen the noise. I can not say whether or not performance was effected with the addition as I did not choose to put them on mine.

Again, congrats.

No cats in '07. Started in '08. Muffler change was made in '07 with the polished tips and no more "hotdog" muffler. I think the 496 engine remained cat free till the end of its production run.
