Has NPP changed for 2009?

I read in another post where someone mentioned the NPP exhaust sounding better on an '09 as opposed to an '08. Is anyone aware of any changes to the system? I hadn't heard that there were. Thanks.

A MTW switch makes all NPPs sound better. I wonder who makes one?

No changes had been mentioned at the engineering presentation. I will note that doesn't mean that there weren't any. They will make running changes all the time. Most never get discussed until someone does a direct comparison and brings the difference to light.

Maybe it's just me, but I think my normal idle sound on my 2009 is a little louder than on my 08. I asked my salesman when I picked it up if there were any changes to the mufflers and he did not think there had been but he also thought it sounded a little louder. Since I had my 08 there while picking up the 09 we tested them both and thought the 09 did sound a little louder. But it could have been just me thinking that and my salesman agreeing with me.
