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.-Tim

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.
